Can't hate it
While this was really not a good game for me, it actually did have a bit of an appealing factor. I think it was because it did have some creativity with the colors and everything. The main fault of this game is that the artwork is just too sloppy. The colors just seem to go out of nowhere and it never leads to anything. The music is weird, maybe next time you should look for some music that is more appropriate. The game also seemed to be slowed down a bit, at least on my computer.
The good parts were that it actually was a pretty good idea, just not executed well. It seems like these enemies could have some really cool designs and distinct styles of attack. I even like how the main guy attacks with the arrows out of his fingers or something. The background could be more than just a solid color. I hope you try harder if you think of making another version.
