While the gameplay was fairly good, there were some definite problems.
#1 - Way to easy. Like, seriously, it was one of the easiest games I've ever played.
#2 - Hit Windows. The enemies occupy vague spaces, which is fine, of course, but the spaces are too large, and they hit you when they shouldn't. Especially the final boss' tail attack, which I was nowhere near when I was hit by it.
#3 - Sound. Seemed a little lackluster. There doesn't seem to be a hit sound effect when you're struck by an enemy.
#1 - It was supposed to be easy. Since it wasn't a serious game, most people may not have finished playing if it wasn't easy.
#2 - Yeah I know about the tail hitting you when I shouldn't but fixiing would require changes to all the other attacks and enemies, since most run off the same class file. I can't think of any other enemy or attack that hits you when you're not touching them. Oh and Asylus isn't the final boss, you didn't play it long enough, even though you said it was too easy.
#3 - I could have added a "hit" sound effect but I didn't feel the need to because there are visual cues when you are hit or hit an enemy, namely flashing.
