F. U. N. That's what this is. You are definitely a guy who knows how to make a simple game fun, once the upgrades (and the xp) start flowing, it just gets better and better. Basically play the Goku looking guy for the dog and always be on the lookout for the temporary powerup that sucks all the xp to you.
Anyway, cool soundtrack but rudimentary graphics--drawn well and distinguishable, but static and stiff. I'm sure you would have animated more with more time. Good job
