This game is pretty fun! (and hard haha) The concept is simple but tried and true, and I like the energy you have to collect as it adds a little bit more depth to the game. The only thing I would change is the fact that you can take damage right at the start when your ship is really fast, and that feels kind of unfair. Other than that though, fun game!
I would love it if you could check out my submission as well :)
