Hey man thanks for the feedback. The enemies are defeated by bumping them off the stage. There could be some inconsistencies here and there regarding edge detection, if they detect a small gap even if they end up landing on another platform it will still count as them falling off, for example. I'll see what I can do with the camera, as that's something people mention a lot. I've also already been considering a revamp of the lives system so you'd be able to gain more. Right now collecting the nova crystals is just to fill the meter and use blast attack. I will probably add an extra checkpoint to certain levels as well.
