I really liked the idea with the power ups. Graphics are ok but the biggest problem is that controls are really hard to use and music could be better.

Bizarre. It seems you spent the correct amount of time to create the 3D looking graphics, enemies and items, a map, basic quest, and fancy buttons, then stopped trying when it came to movement and fighting...Why?

Seriously, the movement and laser-blast-thing are REALLY annoying to use.

Fix the controls and change a little the music please

First off, Not a fighting game. More of a multi directional shooter. Secondly, it's not a good one. There isn't much to set it aside from some of the really good ones. One problem I found is your Isometric movement. (For example, take a look at the movement of solstice for the nes. Good music, interesting graphics but bad controls.)
You could do a lot to make this game more likable. Give it a story line and some variety in the levels and enemies.

Ok gameplay, but its a bit weak to be honest, there is only one type of attack and there isn't much to keep you engaged.
