A and D or left & right arrow keys to move left and right. Space to shoot music above you. Break the meteors above you with music. Q or M to use your Ultra, which you can only use if your Ultra Meter is at 100. You can fill the Ultra Meter by breaking meteors and Ultra Medals. It also fills up every second. I might work on it once in a while, you never know ;) This was ported from my alt account to my main account.
This game very vaguely is based on Majora's Mask. I mean, there's Link, Clock Town, the Ocarina... and that's about it. Majora's Mask Main Theme is by Koji Kondo, the man who made the whole soundtrack for the game. Oh wait, he made the music for the whole series. The Song Of Storms Dubstep Remix was a remix I found on this project: https://scratch.mit.edu/projects/17561768/ The project has a YouTube link, so I'd rather put the link to the channel instead, but the video wasn't available, therefore I couldn't see it. Oh yeah, for all of you Zelda nerds out there who want me to say this, no, the meteors don't actually appear in Majora's Mask. It's based off of the Clock Town stage from Super Smash Flash 2. The Mirror Shield that Ghost Link has is not from Majora's Mask, rather, it's from Wind Waker. (because the Majora's Mask Mirror Shield is super disturbing and also is hard to make in the really simple Scratch art program).
