Energy loop

This is a simple puzzle game made with PuzzleScript in 8 hours for Ludum Dare 47. The theme was "stuck in a loop". I originally didnt plan on participating, but I made the mistake of checking the theme at midnight ^^ Next thing I know, I had an idea I wanted to experiment with, and couldnt resist the urge. It could be much more polished, but Im happy with the core idea.The source code is very messy, but its available if youre interested. Have fun, and thanks for playing!
