Challenging interface!
I appreciate the inherent challenge these old-school types of games present to players; I respect it. That being said, I would recommend some form of guideline in the game's introduction or, even more so, a permanent inclusion that visible to the player as a helpline.
I will look forward to revisiting this title if there are updates! Great job.
P.S. May you please check out my adventure horror game; I think you may appreciate it!
