This obviously lacks a bit of polish, but I quite enjoyed the vibes, well done! The default godot icon as a sword made me chuckle. Not sure if you're aware, but you can just run through the levels before the final boss without fighting the enemies, which seems a lot easier. Better communicated hitboxes would have been nice. Sometimes I couldn't attack, not sure if that was because I was stunned after being hit, could also be communicated more nicely. The spider itself felt a little unthreatening. The reason why all enemies of the same type flash when one of them is hit is probably that you need to check "local to scene" on a resource somewhere, probably the sprite texture. Overall, though, you did a pretty good job, congrats!
