Good prototype of a shmup. I liked learning that I could lure the enemy ship into my own shots and that it created a different strat than fighting the other little ships. Visually the style is nice but I would change it so the enemy shots are a different color than the player's to be more recognizable, and adding some effects like being hit or picking things up. You have a good base to keep updating this, and I think a little polish will go a long way!
