I like the CTR-screen feel of the game, it has a lot of nostalgia to it. The color pallet is good, and the particle effect on the engine of the ship is a nice touch.
The controls could be a little more fine tuned. Maneuvering the ship is a little abrupt right now, making it difficult to avoid bullets. The boss battle was actually quite well made. It became more difficult, but not too much. The interpretation of the theme was unexpected. I would not have guessed it without reading the description. I am not 100% sure what I got as a subscriber, but you mentioned bonus weapons in the description, so I am guessing the “triple shot” was the bonus weapon. Good job on the game.
