I tried your demo. The visuals are awesome, really nice seeing again some ASCII art (brought me back to my childhood :D).
Regarding the gameplay, there are some situations in which I did not understand what I needed to type. In those cases I tried random numbers which indeed did something but it was not clear before which inputs I could use. Especially when fighting a monster, after I choose an attack and the game shows the hit damage, the prompt is waiting for something for which I had no clue what to type.
Good work !
