Nice. Simple little game. I liked the after image when dashing and I liked the push back when shooting the shotgun. Personally I think things are just a bit too turned up. The controls while responsive, the pushback/dash easily felt like too much. Trying to beat the fire goblins was tricky! Shielding with the cursor felt a little unintuitive but it worked. I wish the shotgun had slightly longer range and less player knockback, felt like I was made out of paper.
Good job on your game! Keep working on it!
