Call me nuts, but I actually enjoyed this. I never played the first version, so whether the update has greatly improved it or the negative comments are from meanies I do not know.
Give it backgrounds and proper platforms and the like (Woolies instead of Goombas and Troopas for instance) and I'll play the full game easily. Good jorb!
Edit: Dang, forgot to mention. It's worth the download just for the Bubsy 3D death scenes. Heck, this game is already better than Bubsy F!"£ing 3D. Ewww.....
