Great game, but Averrath is right.
While you have an original idea that was executed well; it could have been better elaborated upon. Of course, you had a deadline to meet, so I won't be so harsh.
Graphics: You did an excellent job on replicating the Super NES look. I think RedHarvest was right to say that the main character looked like a deranged Princess Peach. However, the spiked ball trap wasn't drawn as well as the rest of the sprites. Did I mention that the blood was a nice touch?
Audio: There wasn't much in terms of audio, but it fit the setting quite well. On the other hand, the music tends to get repetitive.
Gameplay: I usually dislike these defense games considering how over saturated the genre is, but the fresh concept separated it from similar games. While the game had enough to keep it from getting stale; the puzzle aspect was a double-edged sword. It doesn't allow for any alternate solutions, which is a bummer. On the other hand, it does provide a legit challenge without being too frustrating and obnoxious. Plus, Rhoneoceros is right to bring up the click detection issue, which is also annoying.
The Good:
-Addicting
-Nice graphics
-Fitting sound
-Interesting idea...
The Bad:
-...but similar to FFMC: My Life as Darklord.
-The puzzle elements are uneven.
-Could use some more variety/elaboration, but that's what sequels are for.
Overall: Here's a nine from me. (4.5/5)
