Some of the platforms were pretty hard to time just right, but I was able to do it after a few tries. The background art was pretty cool and I liked the jump pads and using those to reach higher places. I think overall it's a good base game to build a platformer game on.
Thanks and yeah, one of my friends I sent it too said he was having trouble with one of the platforms so I had to go back in and adjust it a little. Also I agree, it's definitely a foundation but it just isn't too much else.
