Hrm...
Well, first off, you have some sweet coding skills,
and I wish I had half the patience you must have to make this stuff.
The graphics were technically allright, although I kinda think your drawings suck, but that's besides the point. They get the job done,
and the gamplay doesn't suffer from it. Had some nice paralaxing backdrops, and that sort of stuff too.
I wish you would have taken the time to smooth out just a few more glitches, when you gave it the "gold" overhaul though.
Minor glitches, that only occur once or twice is perfectly fine, but things like collision detection and clipping bugs get sorta annoying, after a while. Although it's an understandable mishap, falling through a solid piece of ground, or getting "hit" by a falling rock from 2ft away are unneccessary flaws, considering the time you've dedicated to making this game.
Small things like that add up, and lowers my overall impression, but the fact remains that it's an impressive piece of flash, that you deserve credit for. Also, this game, even with it's number of small annoyances, does demonstrate potential, and I'm certain that you'll put all the things you picked up while making it to good use in your next creation. All in all, it's a solid submission. Way better than alot of other stuff on Newgrounds.
Oh, on a final note; this is 2006. If this game is too much for someone's computer to run, that person needs a hardware update.
Please let the rest of us run the "best" graphics, without having to constantly go to the pause menu.
