Extremely buggy: Characters gets stuck on different layers, some fell while the others don't, sometimes they manage to switch places???, very unresponsive jump key, massive lag, "phantom" item (a collected item that don't physically appears in the inventory but still shows an exclamation mark like it was there, so we can't collect it anymore?), sometimes when all our crew is dead, the game dosent end and we lose all collected items and fishs in this run, etc.
This game has lot of potential! However it's way too short, and some sound FX would be nice too! Other than that, you've managed to come up with a new, refreashing idea! 4/5
Please try again - load your autosave and just finish the last task. I believe something went wrong during the last update, but it should work now.
