Does anyone remember when I made a Super Mario Bros. hack?

SJ, your problem is you need to jump on it's head, like a kid would. You are attempting to negotiate the issue like an adult, by trying to talk to the koopa. Note that there is no "talk" command in the game.

It's my fault, really. I thought I was still playing Shenmue.

Weltall, is there a way to bring in this feature from the original: after completing a level, when replaying it, you can exit by pressing Start and then Select. You keep whatever items you got from the level and don't lose a life. Is that possible? Or is that baked into the level creator?
