Good game! Not much of a platformer myself, particularly hard ones like this. It controls nicely enough and the levels are varied and well done, but I do have gripes here and there.
SFX for jumping would probably be nice. Ghosts having a bit more tell before they appear would also be good or else they'll just blind side you. Restarts should be quicker and automatic rather than having to press try again, it slows us down slightly with that extra step. A game like this should also have a level select just so we can go back to where we left off instead of right back at the beginning.
The graphics and lighting is very nice, the levels I got through were very nice and well done, the steady ghost sounds are good for timing purposes and movement is precise, I did like the menu's sliding across, though it was a tad slow. Good job on the game!
