Nice little game ! The concept is cool, the gameplay is enjoyable and I TRUELY DEEPLY LOVE how the "menu" is integrated with the gameplay and has the role of a tutorial. That is GENIUS, really. The fact that the first screen looks like a normal menu, but when you click on "tutorial" you realize that it actually moves the ship and you actually were in the game the whole time, that's a 9000 IQ move.
The restart bug is really a pain however. Even if I know what causes it, it's difficult to avoid. I'll come back after the jam to play the fixed version =).
