Mario & Stitch: Part I

I love Stitch. He is such an underrated fuzzy alien dude. That's a really good character graphic and it's nice to see someone is using it. The story is pretty generic but for the intent of having a crossover, it works. Now it wouldn't be right without Hawaii somehow involved - I see you have that in the form of that house scene and the picture with the crab. Is there some sort of travel between worlds involved or is every island going to have a very different theme instead of being true Hawaii, with the first island being more like Lilo and Stitch's home? I am looking forward to seeing what you have planned for an overworld and how it ties in with both characters.

For your title screen, the characters are fantastically ripped. The font for "MARIO and STITCH" suffered some loss, but I think you can touch them up in a tile editor to give anti-aliasing to the text, outlines, and shadows - no need to rerip. The bonus room background is very smooth and shiny - I love it. As a stylistic preference, I like the style you chose in the final screenshot. If something sticks out like a sore thumb, it's the Kirby's Dream Land 3 foreground set. It's a nice set, but see if outlining it would make it fit in better with the house and characters. I think the bonus room is passable; the pipe clashes but it's not as jarring.

I take it this hack is very recently started since you only show one new level. Do Mario and Stitch have different abilities and will character switching be a gimmick needed for completion of some of the levels?
