Hey that's a nice submission, good job! I do agree with LightningGrey, since you have to "spam" the arrow keys it feels a bit underwhelming and slow. Maybe with some visual feedback, for example animations for movement and attacks, it would feel more complete. I understand the design choice of turn by turn game and I think it's a very nice idea, though right now you can simply rush toward the end staircase and call it a day. Maybe having some sort of puzzle could be interesting and give more purpose to be quick and chose your path accordingly. For example, if we go with the classics, you have a lever to activate to activate the exit point. I think there is potential :P
I saw that you were working on fixes, eager to see more! Congratulation on the game and hope for the best ^^
