SUPER ARISA WORLD

[Gaia]

To me, it was a solid level, despite the controls being tricky to use (WSAD+P to jump, with me thinking that the up directional key was to be the jump button). There's also a hidden "press jump button right after you throw an object down midair for doubjump" trick. Also, you shouldn't be able to walk over the high part at the end of the level, since nothing is there on the other side of the wall. If you added a test boss, then that would work.
