This is neat for a jam game! It's a little unpolished but I think the main thing that would improve it for me is requiring a more decisive input from the player for some things (such as the menu, which seems to have buttons activated by mouseover rather than a mouse click) and clearer feedback when something happens (such as reaching the door to end the game, which pretty much left me with a blank screen - though I assume I'd collected enough arrows etc. for that to happen). I also think the leaderboard does more harm than good right now: the banner at the top covered most of the UI to begin with, and I'm not sure I was ever in a position to enter a score at the end. Still, an intriguing premise for a game! I'd like to see a version where the opening/closing doors make more of a difference, as you mentioned in one of the comments here.
