I like the small filesize, very based. However, it should come organized in folders. Framerate feels low (30 fps?). The ingame graphics look great and very colorful; feels like the menu should match it instead of being monochrome. I think the enemies should wait for you to approach them in the first stage, to give the player time to mess with the controls. Boost should be mapped to spacebar instead of shift. Gamefeel and juice is awesome, but paradoxically, the actual gameplay feels like shit. If there is a strategy to the combat, is it not obvious. You need to have some sort of obvious countermeasures for enemy units.
It's obvious a lot of effort was put into presentation, but ironing out the basic gameplay should come first. Whatever you have right now can attract players, but it will not retain them.
