I really enjoyed the combat, had a very undertale like feel. Very refreshing.
Loved the whole real vs imagined monsters and the topic of someone descending into madness.
Would have liked for movement to be snappier though, turning was quite slow.
And I got stuck on the third level...got all 12 shards but didn't find any way to progress :( entered the "real" room right next to the starting one but that was it, nothing happened and couldn't find another real room.
