Looks great
You've got a nice game coming. Keep up the good work.
Comp specs: PIII 1GHz, 400Mb RAM, 32Meg gfx card
High: 15-17
Low: 18-20
(I looked at the framrate when there were lots of objects on the screen and the character was moving fast - i.e. falling - so the background changed quickly)
Hope this helps.
