Looks ok, but heavily lacks the gameplay polish.
Many things are really confusing at the start:
Why is the green guy the only one who can't jump at all, and also he is the only one who can use red springs?And then out of nowhere where are dark-red springs, which launch you much higher and work with the blue guy.
Why yellow guy can't grab ladders, but the blue one can?
Then there are some complaints about the level design:
Why are some jumps so tight?
Why would you have a blind drop of a spring, which, if it doesn't land, ruins the lever and you have to restart?
Finally, the game physics:
Why while I move things around they can just go through the other heros?
Why sometimes the character just can't push a certain spring as if it is stuck somehow?
Why the square projectiles made by evil wizard still kill you even when almost invisible?
Why those squares slide along the ground and not disappear upon collision with the ground?
