Personally I don't like this game but mainly I want to point out this has very awkard controls, almost like they are set up for this to be multiplayer, preferably you could add a function allowing players to change the controls.
This game is horrible, firstly to balance it a little make the arrows at higher levels fire a lot slower, by holding down all four arrows then clicking off the game I can hold back anything making the game pointless.
I can't help being annoyed at the fact that you can't micro. i've never made a flash game before so it may be an unreasonable request but it gets annoying not being able to target enermies.
Nice game, although in the disco ball level I found it easier to stand in one place and jump when the light came up. Is that how you intended it to work?
