Thanks! I had really wanted to use this as a platform to experiment with platform physics, I was thinking of making something along the lines of differences between the NES/SNES Mario games and how much in air acceleration they had and what not. Glad you enjoyed it!
A skateboard sounds like a fun idea! I had wanted to make a fast flying vehicle level using some of the other assets in these tilesets, but I didn't quite get that far hehe.
