Thank you for your feedback and the bug you found with the keys. We couldn't make them bug during our testing, so we thought it would be a funny little gimmick, but we will have a look again. We have planned to add more physics based objects like chairs or vases for the player to throw (at the monster) to stun them and to add some physics based puzzles to the game. So once again thank you for bringing that to our attention.
Regarding your other points. We have already put them in for the update after the game jam. Please feel free to check the game out again once the update is out. We would appreciate your feedback :D
