Ohhh, I didn't think about how it makes getting up onto the platform easier as well. That's a good point. I didn't like being able to slip off, since it made some of the 1 block wide platforms hard to land on for me. I wasn't sure if I would have to be ready to save myself in case I slipped off or not.
If there was a zelda-like pause during screen transitions, I think that would be one way to solve the screen transition issue without having to change the level design.
