I like the idea of the game! It's pretty unique and I like that the more ships you have, the harder it is to move, but with less ships, becomes much easier. The art style is simple and retro, which is pretty nostalgic and fits the game very well. The music and sounds were also pretty well-made.
However, the controls seems to be a little hard to control, and the enemies feel quite a bit too hard to kill, but other than that, great work!
