Awsome! Great game design.
I just have a few suggestions for the final version:
1)This guy has to walk a little faster. I can see large dungeons getting real annoying real quick. Maybe a button should toggle run mode on and off.
2)You should be able to attack and defend while ducking, otherwise ducking is pretty useless.
3)You should be able to attack while jumping straight up. I was able to pull off a run jump attack, but not one from a straight up jump.
thats about all I can think of. all in all this is great physics for a great game. I like the little maze and hidden road to the right of the forrest. I definitly want to see the final product!
