I smashed everything in the dungeon.
The game looks good and the style of the environment, the enemies and the UI are very consistent. Movement is snappy and feels good. I love the idea of implementing the solitude theme through the character fighting insanity by talking to puppets and the puppet is very cute, that's super cool, and the way it works through managing your material to maintain the puppet is pretty fine as well.
From my experience shards are a trap ;). I got killed a few times and realised the solution to win was to not using them (I think using the yellow one even froze the game).
I don't like that I can't advance through the dialogs at my own pace and the same can be said about combat. In theory both bars increasing in real-time might work as it should mean you need to push forward but even ignoring the current balance I think one way I would possibly prefer is if Solitude increased either at each step or in the beginning or ending of each combat while life is regained only via potions.
The game is currently unpolished but it's a cool entry, thanks for sharing.
