Atmosphere is great. The Dr. Corvus mini game too hard. I think your game core is story not the mini game. The item which can interact it can show ui for tip key to interact. And then if add run key will better. I don't like repeat walk on same map.
Thanks for the feedback! You make good points, I didn't play around with the walk speed much. I did make interactable items glow a bit, but maybe it is not actually noticeable if you do not know where to look.
