Maybe reset the challenges but not all the accounts and their points. That is, I'd like to keep my gold, torso color, and some of the points.

I don't mind the new challenge sound itself but it stops abruptly. Doesn't really go well with that particular button.

I'm finding it too easy to gain credits from challenge making. Making a similar challenge over and over again could make me rich; spitting out a mass of rubbish challenges could make me rich. Maybe challenge uploads could be "purchaseable". You are allowed to post one challenge by default: If you have enough credits, you can buy more. Then you can remove or upload challenges as you like from your slots.

Another thing worth mentioning are the boundaries of minibash. Kicking off a wall sometimes makes necessary dragging your foot out of the box where you can no long adjust it, I'm sure you've seen that. You can work around this but it's awkward.

Oh, and being squished into a corner until you explode. It's kind of weird the way light kicks can shoot opponents away.

Hm. Also, shading. Art style reminds me of the old Toribash and I think it should be improved in the same way.
