Could have been great, but...
This would have been a really great game if thew movement and attack weren't both controlled by the position of the mouse... In the fourth lvl you just have to spend to whole time escaping loads of missiles, and never have a chance to get in a shot...
It may be doable, but I think it is so hard it loses its entertainment pretty quickly...
Maybe make it so that you can control the movement with arrows, and I'll give it another try!
You still get the points for graphics and story and stuff!
