I like the classic style menu and general presentation. Good to see an options menu, but a volume slider would be nice. Impressive amount of stats and rpg mechanics for such a short period of time! I got stuck in the first room. I feel like I am very dumb. Usually I'd blame the game for this, but judging by the comments it looks like you're doing some proper classic dungeon crawlery stuff here... hey, I got to the trees!
Unfortunately the gameplay is quite esoteric, so I'm going to leave it there. I quite like the presentation and the menus, and the music is nice too. Nice job!
