Using mouse to jump like this is an interesting concept, but it doesn't work very well. Other than that, this is just a basic platformer game. Nothing to see here, really.
This could be better...
A nice fun game with some snappy music, very nicely done! I've only got a few suggestions:
1) No need to tell me the bomb cannon is dangerous in level 2, I'll figure it out myself.
2) How about adding a timer next time for some added challenge? If you do, then make the apples optional for bonus points to give endings and extra goodies.
3) I think the jump could be a little more powerful. I almost have to be pointing straight up to get on some of the platforms in the first five levels, and it's a little frustrating having to jump 3 times just to reach a single platform, let alone 4 or 5...
Again, great game, and I look forward to more like it!
