I'm happy that you like it, I'm actually kinda working on making this an "actual" game. I'm not working on it full time, so it might take a while, but I know this is something I want finish. I already have some new ideas & I was already going to add level editor, but didn't even think of making saving system, which I'm definitely going to implement now too! Any other great suggestions you might have are also welcome ;)
Oh, and I was indeed aware of the rotation thing. I felt that 360° in 0.1 seconds would be too fast, so I decided to make it 0.5s minimum, but left the Wait 0.1s trick as a "prize" for thinking outside the box or something.
