I feel like I am fundamentally misunderstanding some game mechanics. Mud-skipper seems impossible to me (I know it has to be possible, I just don't know how to do it). The next level, in theory, should be simple since you can only go up or down. But I can't figure out how to get the two keys right at the beginning without losing all my speed for the end to get that super high key. I'm just lost. Its a hard skill-cap. If you can't figure it out, then you just can't even play the game anymore. Its a fun game, but I think the challenge level might be a bit too high. That being said, its a very well made game. Just something I am not good at.
