Now THIS. THIS is a platformer. Absolutely love it, though the difficulty does get quite up there. It's a good, exciting kind of difficulty curve though.
I notice a lot of your games have a very retro look. How would you like to collaborate on a more graphically complex platformer with more of a story? I'm decent with pixel art, spriting animations, and story-writing, and you have brilliant ideas for game design.
The response to controls was fantastic, and the save points were placed just close enough to be helpful without making everything too easy. It's really hard to be critical. This was excellent.
