Wow, if you did that in 4 days, you have all my respect. The moveset is great. I initially had a problem that the camera was freaking out after the first climb action (in the Browser) but started to work correctly, once I pressed escape and entered the mouse into the screen area again. Also, it must have been a lot of effort to help the player not fall down by jumps. It has occured only once to me. The only issue I had was the turning with A and D. I found it (too) difficult to control. But once I used the camera rotation with the mouse, it worked very well. Very nice entry to the Jam!
