Nice, I know you made this game to get better at programming, so graphics don't matter, but still I think you have to work on both of these skills at the same time, and I don't mean that you shouldn't use simple shapes, in fact I like games that use simple shapes, I just mean that a color pallet and better UI, and maybe some post processing would have went a long way, and one more thing, I noticed that you made the camera a chilled of the player, witch is fine but it can make the camera move in some ways that are uncomfortable, I recommend that you try Cinemachine to set up your cameras going forward, it's really easy to use and looks great, but really am impressed, your improving quickly, keep it up!!!
