This is the first game I've ever made in Unity without following a tutorial. I know it's not the best, but I'm proud of myself for being able to finish a game.

Great work. The balance between ammo and the base life is quite fun.

This was really fun! The ammo being used as the same resource to kill aliens and keep your base alive is a cool concept. I also liked the retro music track and sound effects.
