This is probably how the game works, but there is a pretty severe momentum issue. If you are not crouching, your momentum will be reduced to walking speed, making some jumps pretty difficult to accomplish. Example, the first jump in "Escape 1", if you land on the platform without crouching, you will not be able to make the second jump. This may be how the game works and was developed, but I feel like this should be changed. I like the idea of gaining momentum by crouching, but losing momentum while not crouching is pretty obnoxious while trying to enjoy the game. This is just a problem I personally had with this game and it would make me happy if this problem could be resolved.
Thanks.
