Hi, congrats on your game! :) Regarding the art, I'm not sure if it's yours, but it's perfect. I really liked the overall style. As for the gameplay, it's simple but well executed. I believe it could benefit from a few additional gameplay options to make it more interesting.
If you have some spare time, please try out my game. It's a classic space shooter from the 80s but with a personal touch. Please leave your honest feedback. :)
