Thanks a lot for the feedback! It's impressive that you managed to score 3 stars using a mouse (I mostly used a controller myself).
I agree that the contrast between the bullets and background can be low at some points. I'll look into a different laser color after the game jam.
You can use mouse to restart the level. You'll have to double click though. I used Godot's `ItemList` for the menus which has that behavior. I'll swap it out for a bunch of normal buttons so that single clicks will be enough. I agree that double clicking is non-discoverable and annoying.
