I am not a professional by any measure. There are no guarantees that this will go anywhere, because I'm just some guy playing with this cool app that is S&Box.

That said, should I continue developing it... well, I'm not particularly sure what I'll do.
Currently though, the plan is probably some sort of lava monster game. I don't want to make a platformer for two reasons:

I'm already spiritually copying a game called Gravity Shift from Roblox, and I'd just be making a platformer that's way too similar.
Marble Racers already exists and is loved. Not that a platforming ball is sacredly unique and that I would commit a crime for making platforming levels... but I think I could make a more creative gamemode that doesn't try to outclass Marble Racers like "Hey Look At Me! I Have A Cute Gimmick!" or something.
