I beat it, it was fun! Pretty impressive for your first ever game.
Some notes, I did run into a bug where the game window wasn't centered on my screen. I'm assuming there was an energy bar and a health bar on a HUD but I couldn't see those.
If you ever turned this into a bigger project, I'd play it! As long as you ironed out the controls a bit and made them a bit snappier / more responsive.
