Funnily enough, the glitchiest/hardest parts of the game are where you're supposed to walk onto moving blocks without jumping, which I think is a testament to how perfectly the jumping controls are nailed down.
There should be an adventure in AA where you can sell special items from the Battle Arena, such as Crystals of (Ultimate) Rarity, enhancer fragments and such, because I don't know about anyone else, but I never use those and could use the extra moolah.
Not bad, but two things would greatly improve the game. First have a map. That way, you can tell whether or not the edge of a screen you're heading towards actually goes somewhere. Second, if the edge of an area actually DOES go somewhere, have any open space touching the edge of the area lead to the next area. Accessing the adjacent area is really hard to do if there's only one square that leads there. Other than that, thoroughly enjoyed the game and look forward to a sequel.
That weird cat kind of reminds me of the one from Super Pitfall on the NES. It's equally as useless to the rest of the game. At least the music is cool. :)
