Sometimes I try playing SRB2 with one hand. Because I'm eating pizza, not what you're thinking.
How about Broken Knuckles? :^)
(the premise being that you can't move normally as knuckles and have to resort to jumping, gliding, and climbing to get through the stages)
Do a whole playthrough as Tails without flying
I could beat GFZ1 without jumping at least.Beat the entire campaign without jumping.
Pushing record attack and working on all characters would seem to be the most obvious here.Yes, i know, there are the typical challenges, like Not collecting rings, one life, killing all the robots, and the boss rush. But I want something to do, because I have completed my save, 100%, and i'm starting to get bored. any Suggestions?
