I like the aesthetic a lot! It feels pretty good to play but some thoughts i had were that it didnt really need variable height based on how long the button is held, i only say that cause i always felt like i was going to reach a one way and then i didnt and i didnt even realize i just had to hold the button to get up to it. I think the wall jump tutorial might be a little tough. Also colliding with reflected bullets still has the screen effect so you might want to remove that, im guessing you already know about that . It is very fluid and fun though overall!
