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

Please continue work on this! Maybe in future you can add different levels and (possibly) the ability to move the camera e.g. rotate it around your character and a first person mode would be AWESOME!
