Wow, thanks a lot for such nice and detailed feedback! Really happy you enjoyed the gameplay loop so much! And sorry it took more of your time than anticipated! ^^;
Indeed, the main objective is that no player would have the exact same run, but you can still learn some pattern in the way the world is built. The monsters not hurting the player while idle is intentional: I did try it the other way round (hurting you even if you're not moving), but I thought it was unfair, especially if you're planning for the best route and it ruins your plans and takes more steps out of you. That and the fact that they move at random made it even more unfair.
You're not the first one telling me about the font, and I did realize that to some extent, but I still think it's acceptable since there isn't that much text and it fits the overall aesthetic. What I did to make it more readable is leave two spaces instead of one between each word
Thanks again and glad you had fun with it! :)
