Daaaaamn!! For 10 days that is mighty impressive! I love the art especially!
I do feel the "battles" go on a little too long. They're really challenging at the beginning but once you've gathered a good reserve of power(?) it just kind of gets laborious. That's really my only issue I have with it in its current state. But aside from that, this is a very very promising concept!
Best of luck to your future endeavors!
