Solid game! I didn't get to the end because I couldn't really find a way to get past the enemies without taking damage, so I kept dying to them. Overall, I liked the game and didn't find any issues other than that!
No worries! There really wasn’t an ending. The bottom floor just has a ladder up! If I end up iterating off the code used for generation, I’ll definitely make hallways wider. Glad you liked it, and thanks for playing!
