Hi, congrats on your game! :) I really enjoyed the theme of the game, it reminded me of some classic Flash games from the 2000s. One thing that I might adjust in the game is to provide a better introduction to the mechanics. Perhaps adding more levels that teach new mechanics, or maybe just a single "tutorial" level when opening the game that teaches all the mechanics.
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. :)
