I love everything about this game, it's only flaw is being too damn short. I'd gladly pay 20 bucks (adjusted for inflation) for a feature-lenght version.
Wish you the best, I'll be following your work!


This game is outstanding! Everything from music to gameplay are so amazing that I almost forgot everything around me.

Btw, the game is better enjoyed if playing yourself, but you can watch my 4K gameplay if you don't have time to enjoy it.

it is very beautiful thank you for making the game and leaving it at 'give what you want'price !!!


There is no ammo in the pool, so I can't finish it. I'd really like to.

Try using the gun on the girl



It swallowed me whole, like a delicious spine-tingler found in a dusty old bookshop.



While some of it's story can't compete with it's stylish visuals, and the gamepaly needs work, it is none the less interesting enough to be seen to the end- which won't disappoint. 


great voice acting, really love the color pallet. This is just as good as Scriptwelder's games, if not better. 

damn! the colors look awesome! best game ver bro!

This game is awesome! But I can't finish it though, it crashes and exit...


Dang. Sorry about that! There was a known crash bug if you quit and then continued the game at certain places (usually on the boat). If you think that's the problem, and you're keen for more you could try just playing straight through from the start without quitting (mash esc to skip through dialog you've already seen). 

It crashes when I returned to the island, between the lady zombie spot and when I try to get an item from the waterfall. I can't recall it very well, and now I can't open the game to see for sure. 

No worries though, I will try to reinstall the game and see how it goes.


Just wow.  So much better than a game like this has any right to be!  My ONLY suggestion would be to add a button to show objects you can interact with as there were a few items I didn't notice.  10/10

Hey Powerhoof! I made a cringe video on this game but it was very entertaining nonetheless! I love this style of games!

We might be a little dumb and took a bit longer to figure some things out but we super loved this game!  We'll be looking out to see what you do!!

I'm working on a longer thriller adventure game in the same style, but not specifically a sequel to this or Peridium.  Working on longer stuff is hard though! It's taking me ages compared to the gamejam style ones, so don't hold your breath ;)

Any update? This is honestly in my top 5 point and click games ever and I would love to play a full fledged one from y鈥檃ll 

I'm still plodding away on it, but it's slow going so don't hold your breath!
That said, it's almost time for Adventure Jam again, so I might do another quick one for that!

You should make a kickstarter! I鈥檇 totally pay my support ahead of time if it helped make it happen!

Thanks! I don't think we'd ever have the energy for a kickstarter though, everyone I know who's done one aged about 10 years over the month it was active :P  

We're lucky enough to be able to self fund our own projects at the moment. At least until we decide to make a huge Triple A MMO of course ;)

What an awesome game! The plot was gripping! And the narration was spot on! All together one of the best indie games I have played in a long time!! 

hello from France! pretty interesting work but it do crashes for me on ubuntu 18.04 when reloading the saved file .

This is is so good, but it crashes on ubuntu 18 when you enter the camp and meet the ships captain  


This game is Berry Squeezing Good. Get it, Do it!

This was just the funniest thing, had me cracking up frequently with each surprise. Nice job, top game.

What a trip this game ended up being! It went exactly where I wasn't expecting. Great work :D


Gave it a go...

The game crashes consistently when I reach the top of the damn to retreive the ammo.  I'm playing the Linux build.  Such a shame too because this game is wonderful! To be specific is crashes as soon as the words "I see what you're doing up there!" appear on screen.

Oh damn, sorry to hear that. Did you quit and then continue at some point? I think there's a bug with continuing games that I still need to fix, it could be that.

Yes, I saved, exited, and continued the game later on.  I hope you can fix the bug(s), I look forward to finishing the game.

This was the best thing that I've played on Itch, The pacing was perfect, the voice acting was perfect, the style was perfect.
Although I struggled tofind a couple key items due to that style, the game never has any "cat hair moustache" solutions
Everybody should try this game

You guys have knocked it out of the park again! Another corking adventure thriller, really had me guessing every step of the way (wrongly, as per usual) and the payoff is excellent!

The voice acting was pretty special too, hats off to the amazing peeps that helped you out with that, and hate off to you for making another awesome point-and-click classic! Keep up the amazing work everyone! =)

one of the best voice actor series of my game

Played through this on my channel! I haven't touched an adventure game in a long time, but I found this super engrossing. Great work! 

Super amazing game! Gameplay, music, story, and voice acting were perfect! While I'm on the voice acting, the voice acting from everyone in this game was soooo freaking good, like holy crap it was so good! Only had a couple problems, it seems like a poor idea to only let you pull off one piece of meat to feed the dog, especially if you miss what you're really supposed to do with it, I mean, there's arms and legs scattered everywhere, should be able to just pick up another one. The other problem was after I reset the game because I threw the meat without putting the painkillers in it, it crashed when I got picked up by the boat. Still a super phenomenal game! Made a video, hope you enjoy!

Ah sorry about the crash! You can use the cleaver to get more meat, but it's not a very well signposted puzzle, and the visuals make it pretty unclear so a few people got stuck there.  Thanks for playing!

The game crashed on me when I met the captain :( You want me to send the crashreport somewhere?

Ah, sorry about that. I suspect there's issues with the save/restore system, I didn't have time to look into it in the jam. Did you save and quit and continue later?   If you're happy to send the crash report to dave@powerhoof.com that'd be super helpful!

Sorry for the delay. You got mail. As far as I can remember, I never saved and loaded, just played right through, but I see a "Save1.sav" so probably I saved. Or the game saved on itself? I don't know :)


Alluvium is a micro-masterpiece, being relatively short, but great in pretty much every way it can be. A pixelated art style and variety of bright colors mask an increasingly grim world as you point & click your way through a constant barrage of life threatening danger, all while the excellence that is Adrian Vaughan's voice guides the way through the story. I did click myself into a corner at one point, but once I corrected things and reached the ending, I was left definitely wanting more.

Great job on this, devs. You made a point&click adventure...exciting.

Hey Developers, I played the first like 7 minutes of the game and all I can say is I am blown away. Seriously good job! The narration, the characters, the vision or foreshadowing or whatever when you do something that is going to get you killed... Excellent job! (edit: Just finished the game, you've got real talent, I'd love to see it become a full game!)


Super fun and interesting game!!!!


CRAZY NON STOP, EXHILARATING,OVER THE TOP EXCITEMENT!  Really that was very good, the voice acting is fantastic, the tone and theme all flowed very nice, and at any point it could flip into something new.  Really enjoyed this, great work


Awesome art, amazing vocals and a story that''' make your head turn so quick you'll decapitate yourself.

Brought to you in a tidy little bundle of a game.

Good work.


great game!


I just love this game. 10/10. The voice acting is also great. :) I Hope you make more games like this!


Another marvelous adventure by you guys! <3 I really loved the voice acting by Adrian and Sally - they've been such perfect counterparts and filled their characters with life. :) The whole art style left me super excited as well. The colors, all the little details... Stunning work. I suppose you'll score another high ranking in the Adventure Jam 2018 with this little baby. <3 I wrote a laudatory article about your jam game and also uploaded a playthrough video for anyone interested. :) Keep up the wonderful work!

Best wishes,
