Aiming while moving is very tough, and the graphics seems a bit stretched when playing on web browser.
That aside, nice job making your first every project. The good news is your first project is behind you, and the better knews is you will only make better and better games from here on out.
Some positives: Dialogue was nice, art was indicative enough and controls were intuitive enough for me to know how to interact with your lore NPC. The attack style was interesting, and for a first project you have quite a few mechanics in place
Some areas to improve: Sound is super important to sell anything. Some SFX would help. More distinguishable level graphics would also help indicate that progress is being made. Also some indication on which way you're facing so its easy to know how to attack.
Anyways, feedback aside, keep making games, they'll only get better and the learning you'll do along the way is invaluable. Good job!
