Pretty nice game, very easy though. Encountered a game-breaking bug the two times I played it. At some point the interact button ('E') stops working. Both times it happened after killing a tentacle, not sure if that was a coincidence. But after that, the 'Interact' label is not highlighted anymore with anything (tombstones, chests, etc ...) and it doesn't work anymore either, although the character does make the interact movement. So the character responds, but the environment does not.
Nice, will give it a go!
Edit: Fixed indeed, made it to level 10 without encountering the bug. Found another one though, after killing the boss, it takes very long for the blue chest to drop. And, if I go back through the entrance of the arena, both the entrance and exit close again and it shows 1/20 hitpoints for the (already dead and gone) boss, deadlocking the game.
