Aight, first off, this is a good game, but MAN IS IT HARD! (I saw that you're planning to add in Difficulty options in the future, which is a good thing.) Also, why is the Powered Up OST not an option? (Especially considering this is basically Powered Up, but if it was more Retro-styled, had some different features, and was MUCH HARDER.) Finally, Controller Button Mapping should maybe be a thing.
Thx Dr. Smug, maybe I'll implement the Powered Up OST in some way, however, I have considered since the start that I could implement multiple games in the project, like lets say 1 and 2, there was never a sequel for Powered Up, so the extra music would need original remixes...
And yeah, I should add gamepad remapping, I'll put it on my list
