Ehh....
I liked the concept... But difficulty was a problem for me... I don't usually take away so many points for difficulty. The reason I did was because not only was it so difficult I felt like there was no point in stressing myself to get past the difficult parts. I found wall jumping to be unruly at best. But the concept was amazing maybe go back and really put some time into this. Give it a story and such, and compel me to want to pull my hair out. xD
