SNKuro already pointed out the issue with minimized versus full screen. With that said, there is not much to test with your prototype, but I'm still hopeful to see how the game turns out. I'm interested to see how you will relate your story line to the jam theme.

Need to work on the optimization. When you have it minimized you can't place the tiles but when you fullscreen the game you get the options but only see a small portion of the game. Despite these things the prototype looks promising and I can't wait to see the full game!
