Nice original game. I did like how every character's ability could only be used once. It felt like I didn't really need any character other than the key. Every level I was able to get though with only one ability using the key character the whole time. I think if you designed the levels so you'd actually need to use more than one character that would really help or even if you made it so ALL of your party has to get to the end so you gotta open up paths for the other ones, like the jumper can go over a wall and open a door with a switch there then the key could unlock something in there but now the bunny is stuck on the other side so you gotta find a way to get him out. I feel that stuff like that would really improve this game.
