wow! that was a really great pla former with a twist as you say :) you managed to implement something other people did but way way better, and it all comes down to level design.
the level design was fantastic!!! level 3 and up really shines on that, and the difficulty ramp up is also great, design wise.
The art was also simple and fun, not too hard on the eyes.
The only thing i would change is the jumping speed, its super slow, and its the first time i really see a good usage for different heights when u leap up from standing, or jump to a certain direction, really works in this game!
Good job to the entire group!!
Please play/rate my game too :)
