Yeah, as genuinely fun as You vs Boo is as well as the additions for challenge mode, the screen crunch on this is absolutely miserable. Levels that are only kind of challenging as someone who has played SMB a lot become hell on Earth because I didn't slow down in time to not crash into the goomba offscreen. Probably pretty cool for its time though, I definitely would've played the shit out of it if I had it when I was younger, but outside of running through the You vs Boo levels it's just not worth it.
