It took me a while to figure out that I was the block and NOT the crossfire, but after that, it is a pretty neat concept. However, I think the crossfire moves WAY TOO FAST, and it is really hard to make it past the first few seconds. I couldn't really test out the change time feature (because of that darn crossfire), but after checking the info, it seemed like a very interesting idea. But I do have one more problem- the controls. There should be multiple keys to jump and move, like the arrow keys, and W to jump, also the time change keys are in a VERY inconvenient spot, and it is very hard to move while trying to use it. You get a C+ from me, and please check out my game if you haven't rated it already, thanks!
