Thanks for the review. Yes, this project was way too big for a game jam. I would not consider it a game yet. The Asteroids won't respawn currently since I am only able to do an initial spawn and then the wandering 3x3 grid for the spawn areas was not finished. .. My main focus was learning new things and trying them out.
The controls feel a little sluggish, but it was intended to be an inertia-based game. Turning yourself is super easy, but changing direction is very hard.
But as said, there is not much of a game yet. :-) I am surprised about the no sound. I might need to upload a Windows build if the WebBuild has issues. There should be hit sounds when you hit an asteroid, the collecting sound sadly did not work.
