I have an idea for a 2.1 kind of update or maybe when the game fully releases:
Add an Online Mode kind of like SRB2 2.2.10. There could also be server ranks, like Guest, Member, Admin, Co-Owner and Owner with different commands for each. I think this will give the game some more playability and will hopefully get you a lot more downloads. There could even be gamemodes, like battle mode or race mode. I hope online functionality isn't too much for you; and just to let you know, this is just a suggestion.
