Neat game! I would recommend, even if just text, to add the controls into the game somewhere because I don't usually read the description before playing. I thought the mechanics were cool, although it felt like you are always turning too wide because the enemies mostly just beeline towards you which means they remain really close. I think having a bit more variance would be a lot more interesting, if they were coming from the side or from in front. Because of this also all the enemies are slower and you can just drive in a line pretty much and avoid enemies. I liked the combat although there needed to be some feedback for getting hit as it was difficult to tell. Overall though great job.
Also just a brief tip I would recommend turning the itch.io fullscreen button off in your game page because Unity WebGL has a built in one and it interferes with Itch's. If you want to disable Unity's fullscreen button in the future you can also change the format to 'Minimal' in the build settings for WebGL.
