Nice work. Graphics, enemies, and powerups are very polished. The controls are awkward due to international (dvorak) keyboard layout. Super Mini Jumper and Cheesecake Hero, which I played a few days ago, would both benefit from leveraging physical key values (KeyboardEvent.code on MDN) to make the controls layout-agnostic. This will expand your audience to other countries.
Fix that, and then I suggest start spreading word of mouth (in the real world) about your games, with a mandatory price tag. Pay rent and bills with your work :) You got this.
