Hi, congrats on your game! :) Great game, it reminded me of the classic Flash games from the 2000s. The only addition I would make to the game would be to display the distance covered during the game in the HUD, not just at the end. And maybe add a scoring system that increases by performing maneuvers.
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. :)
