No, seriously. I had no idea how to double jump so I made it easier for people who also didn't know you could double jump... would've been so much easier if I knew.
no wonder I had so much trouble, since my first run was technically a challenge run, but the only real place I had major major issues with was the last stage since there was a platform with a one block gap where a single jump is needed for a very precise moment, I got so mad I moved the block.
