While I like the idea, some elements fall outside the screen when the aspect ratio is not 16x9. (had to use 640x480 to get a decent framerate on my work-pc)
Sorry you ran into performance issues. I admit the demo isn't as optimized as it could be and the UI elements need adjusting for different resolutions too. I plan to address this in the final game (and hopefully in the demo too, time permitting) :)
