Control the game using the arrow keys. If you manage to find and clear the hidden stage, please let me know in the comments—I'll follow you! Just a heads-up: the hidden stage is tucked away where no one is likely to find it, and even if you do, it's extremely difficult. I put a lot of effort into making this, so please spread the word! I probably won't be replying to comments. I'm resharing this after spending some time fixing bugs.
