Wow, that was a great game! I will admit it got very annoying with those little green guys. I was able to win with Luna rather easily. Zelvy was a lot harder, though. The graphics were quite nice. Sometimes you just had to stay in the same spot and just keep on firing over and over.
There was some great variety for these enemies. I loved how you could teleport when you just reached the border. I almost forgot it was a dungeon. These drawings you showed were very nice too.
