I see you entered your game in Pixel Jam! Nice! Good luck!! I guess it's too late for the Jam, but I just wanted to remind you that there is still a bug in the current version (at least for me).
Start the game, then walk out and get killed by something, then select "Main Menu". Instead of going to the main menu it just exits the program. Also, selecting "Exit" does nothing.
So it looks like the "Main Menu" option does what "Exit" should, and the "Exit" option does nothing.
Again, good luck in Pixel Jam!!! I am sure your game will do very well!
