I tried your demo! Killed 25 blob monsters. Looks like you got all the basic elements. I like how the trees turn transparent when you walk behind them. I think some of the attack animations could use improvement. Are those boulders the good knight is tossing at the blobs or some other projectile? I would also make the sword melee attack more pronounced -- the animation looks really short range and when you have unlimited boulders to toss at the enemy it doesn't give much incentive to use a melee attack.
Excellent progress for one week of game dev!
