A downloadable game for Windows, macOS, and Linux

The flood is coming.
You must hastily piece together a raft and escape the looming threat of a watery grave.

Work alone, or team up with (or against) up to three friends!

Note: the Mac and Linux versions of this game are sadly untested, and may suffer from gameplay/input problems -- or they could work just fine. Let us know in the comments below if you experience any issues.

Requires 1-4 gamepads for multiplayer. With no gamepads plugged in, the game is single player, and uses the keyboard.

Left stick / WSAD: Move
X / Space: Jump
Right trigger / Left Shift: Grab
Circle / E: Glue objects together
Left Trigger / F: Arms
D-pad / Numbers 1-4: Emote


Made in 2 days for Global Game Jam 2017, for the theme "Waves", by:

Liam de Valmency: Design/Code
Richard Tongeman: Art/Visuals
Alex Jones: Music
Lewis Thompson: Sound

Will a generic usb gamepad work on this?

noice cause xbox 360 controller worked

Its  very good to play and if u haven't played it yet go and play it now!

how does one start the game(derp)

This game was interesting with just so many weird ways to try to stay afloat! I'd imagine it'd be fun with friends...to sabotage them of course. 


Very thrilling. 



Sometimes stuff will get stuck in the ground,make objects that are inside the terrain get non-stuck

Pretty neat my friend rage and almost broke my controller XD LOL


i cant move please help

what are controls for xbox one controllers

Cool game!

(Umm... Is it just me... or does the “island” actually look very much like the back side of a naked body???)

Looks fun, one problem... I simply CAN'T CONTROL THE CHARACTERS HELP

One of the best indie games i have played


cool, really neat B )


Am I the only one that saw a shotgun on the left side of the island

Made a video, It was SUPER fun!


how do you open the game

lets give it up for my amazing photoshop skills

Trying to survive a flood has never been as fun.

Very cute! I can only recommend it in co-op!

new subscriber :D

For some reason when I connect two controllers,

They both share the Trigger buttons...

This is extremely annoying since the whole game revolves around using these trigger buttons

Any fixes or suggestions?

This is a fun way to pass time with ducks. It also has some nice music going on. Recently tried to make a raft out of all the things and...that's more difficult than it sounds. Physics get weeiird when you do that. Good job ducking.

Fun little game, pretty damn good for 2 days! The missus and I had a good laugh playing it.


Can you help me? Can you make it compatable with both keyboard and Gamepad? PPPPP


does this work with dualshock

Yep, should work fine. If you have trouble, try using DS4Windows

I BEAT THE GAME :) If you're wondering what's at the top, check this out!


Awesome little game, loved it! Great idea!

Hope you liked my let's play! I kind of cheated ;D If you did like it, help me by subscribing to my channel. Stay tuned for daily uploads!

Thanks again and check out the game, it really is fun!
