Apart from the bugs you already know about:
It seems the player doesn't take damage
Enemies can drop their spice below where you can pick it up
Enemies only drop one kind of spice? What's the point in adding spices if you only have one option?
Artstyle is probably your game's strongest point. Unique and charming. Gameplay is confusing and difficult to understand, but once you do it feels repetitive and without purpose. Like, what does each minigame effect on my weapon? Music is okay, just feels a bit busy.
No idea how you managed to raw-code HTML5, that's bonkers to me.
Hopefully I gave a bit more action-able feedback, more than just "This good."
