Bugs I have encountered:
Escape will not bring up in-game menu, so the process has to be killed every time
Re-binding the menu button not only didn't fix it, but after that you can't rebind back to Escape, even after 'Reset Defaults' :/
Can't put raft in water
Got stuck between an invincible tree and an unclimbable rock, couldn't commit suicide, restarting put me right back there. The only solution was to start a completely new game
TLDR; this game is currently unplayable. A real shame, since when it does work, it's fun.
