You've really captured the feel of old-school roguelikes! It was good fun to have such an extensive amount of control, especially being able to do everything via the keyboard, without having to memorize a full keyboard's worth of controls like in classic Rogue :)
The gameplay is solid, although definitely on the difficult side for me with early fights killing me frequently before I was able to get any equipment. Would be nice to have a listed HP stat to help making decisions as to when to run away. I also found that my character wasn't healing when sleeping, but would forget spells from the previous day?
I loved the names for each of the enemies, it added a lot of character. Keeping the classic mystery potions from the original Rogue was fun too!
Some music and sfx would make a huge difference when you get the chance to add them.
