Personally, I like the game. It's a new idea and well executed. I also like the idea of having it take so long to unlock all the characters...it gives you something to shoot for if you want to continue playing. Now...tying a badge to 36 gold characters was probably not the best idea...but that's not the developer's fault.
Okay...is there supposed to be text on the "Continue" screen between floors (like their was in the original)? If so, it's not showing up for me: firefox 2.0.0.14, flash 9,0,124,0, linux
4/5. The only thing keeping it from a 5 is a really annoying bug. If you die on an important enemy (e.g. Bandit King) and load the autosave, you miss a chunk of the story.
Minor bug...if you're in the middle of doing one trick, and hit the button for another trick, the initial trick will get scored as the second trick. For example, if I'm doing a Double Grab, but hit the button for Whip in the middle, I'll get points for a Whip (which is worth more) without ever actually doing one.
