Cool concept of having the boss approaching with each step. I like the retro art of the asset pack you used. It was cool to explore the environment and seeing what kinds of enemies and items I could find. I never did find out what's in that staircase the spiders are guarding but I'm considering coming back later and trying the game again to find out.
I did encounter an issue where I fought the slime and we got into an endless battle of me blocking and him healing, so the battle never progressed or ended. I just had the sword, basic defense, and the food that heals with each step when it happened.
Would love to see a version of this with a bigger environment or even a randomly generated one. Nice job on this submission!
