I like the graphics, the flying loop is a bit choppy though. I really enjoyed the background music, but I wish there was more tracks than just the one song. (Although, I think you could really pull off the looping you have going on if you cut the intro and outro. I don't like the fact that the background is just straight from maplestory, (Come on, you can be creative...) Different backgrounds would be cool. Maybe a better system to move you from one level to the next would help the player better understand their goal. (People like it much more if there is a clear goal for them.) So like for example, maybe give them a world map to start the game with and let them move from one level to the next and make the background of the level match the part of the world map that they are on. BADGES!!!! Yes!! Badges, achievements, trophies whatever you wanna call em, people love em! Last note, maybe make a reason for why we are trying to get to this Dark Necrobat.
