Over all, I think this is a decent puzzle game. I think the aesthetics work very nicely, and the sound design was good.
That said, The instructions were not entirely clear for me. The part about “If the anomaly is removed I should try sleeping again.” suggested to me that I should remove the anomalies before sleeping, which isn’t the case and threw me off for a little.
I will admit that my confusion over the detection tools on the left and removal tools on the right was partly down to my mind not clicking with the statement (as in, it totally didn’t register with me through no fault of the introduction).
If you were to continue working on this project, I think an optional tutorial “level” would work very well. Basically, tell the player exactly what to press to detect the tutorial ghost, where in the journal to find the what to do about it, then exactly what tool to use to remove the ghost. Something for the smooth-brained players (such as myself) to get an active idea on what’s expected of me.
As I said in my stream, I could see this being a cozy little phone game. Chill on the couch with a phone out and just try to remove the ghosts!
Here’s a link to my stream of the game to haunt your Halloween season!
