Also - if you do increase the scope, you could totally, like, intend the game to be ~10 minutes segments. Maybe release the first segment once you think it's polished enough, see whether you want to add additional areas or environments with more levels and options.
Basically, don't get burned out with scope creep. If you have something that works, release it. Even if you want to add more later. :)
Sweet! I doubt I'll be good enough to manage that but it's cool that you were able to implement it so quickly.
Haven't had a chance to check out the demo yet, maybe tomorrow night.
