I managed to beat the game. It just went back to the STAGE SELECT screen. Not even a CONGRATS YOU BEAT THE GAME! or something? Anything? It made me feel unaccomplished. Because of that and the lack of weapons 4 stars.
Don't get me wrong - I love Nitrome, but his games are way too montonous. This (I think) is one of his best games. A shop would have made this game a ton better. You should have been able to buy new armor, weapons, upgrades, magic powers, special abilities, etc. I think you should have also added combos. I rated it 4 stars but with atleast a shop 5/5.

Yep, I've raised a couple hundred over the past year for various charities :). It's been an incredible way to spend my extra time.
