So... When I started playing this game I got repelled by the graphics, big-time. I'm aware that art takes time to create, but perhaps you should put a little more time in it. I mean, the character has terrible proportions, the rock-throwers and wizards are just build up from squares. The trees have the same pattern, that's transparent for no reason. Not to begin about the log that looks like corn.
Anyways, game-wise, I guess the game was pretty alright, the game certainly wasn't short as I spent quite some time playing it. Bosses were quite well made and had different ways of killing, which was a nice touch, although I got kinda tired of them being in the air constantly.
The animations were alright, I suppose, although the walking loop could really use some touching up. I recommend trying out a walk loop with a stick figure and basing the animation for your current character on it.
Overall, the game was quite okay, I can see it took quite some effort and it had some pretty smooth coding, no big glitches. My main problem is the visuals really, although there's also quite a lack of variation and challenge.
I hope you'll make something awesome out of this.
