I like the artwork, but I think that the portal animations could be made faster since you have to use them so frequently. I also agree with the other comments about the attack hitboxes being unclear, especially on the goblin enemies which were hard to attack without taking damage.

It's hard to say for sure, but it feels like the player character's attack hitboxes are smaller than the slash animation and that leads to attacks missing when they look like they should have hit. For the goblins specifically, I think their attacks either have too much reach or come out too quickly. Making sure that the hitboxes are closely following the weapon sprites should help the attacks feel more fair and avoidable overall.
