Challenging game. I tried 3 times and I died 3 times at level 3 or 4. There are a lot of enemies ans the power-ups don't come quick enough to stand longer (I speak for me).
I'm using Firefox under Linux and I had zero issues. Games made with Godot are the ones working best for me (Unreal Engine being the worst).
I like the music you chose, really blending, not aggressive, not stressing, just active and inviting. The sound effects are monotonous but well chosen nonetheless.
I've seen you used AI for a lot of things in your game. Sure it speeds up the process and it helped you produce such a complete game in such a short time. It also depends on where you are (or you want to be) most comfortable with. I hope you'll rely less on these tools next time and produce more yourself.
J'ai bien aimé ton jeu. Merci.
