You obviously know what you're doing...and aside from all the things everyone has already mentioned a hundred times prior, I have two minor points.
1) -I- don't mind that S is jump, because I like running to doors and sliding in. Although it'd be a nice touch if there were different animations for people who walk up to doors and step through, and people who run at them. It's a niggly momentum thing.
2) Am I the -only person here- who couldn't get the two spirals on the first level? After you've fired yourself out of the cannon, they lie mockingly above, out of reach, and I want to add them to my collection, and I can't, and this saddens me.
