Here in my cave, just bought this uh, new scuttlebug here. Fun to raise up here in the falling rocks. But you know what I like a lot more than upwarps? Half A presses. In fact, I'm a lot more proud of these quadruple new parallel universes that I had to get aligned to hold five hundred thousand units of de facto speed that I built up.
Beyond adding visual elements and cosmetics to your maps (which is always a good thing until there's too much of it), I'd advise you to add some flair to what you already have (the main character, maybe walls and doors, etc). Maybe make the main character something else than just a square, which is really overdone if you ask me.
Good luck!
