Hm... I think there are still a few too many problems to make this worthwhile posting, unless I'm missing something. Maybe you can help:
1. I can't walk up hills without jumping.
2. The speed of the player doesn't make sense. One moment I'll die because jumping over the enemy launches the player off a cliff into the water, when all I intended to do was land on the other side of the enemy next to the water. The next, I'll die because jumping over the water didn't go half as far as last time I jumped and just dumps me in the water. There's no way to jump across moving at that speed. Why does the player move at completely different rates? I can't survive if I can't predict how fast the player is going to move.
3. I don't understand what happens when I crouch. It just plays a loud white noise sound until I get up; why?
4. After finishing the first level, I get an infinite number of error messages and have to terminate GDPlay.
5. There are no instructions included. Is there anything I can do besides jump? Do the things I'm picking up have any significance?
