Playing the v0.5.0 version, I noticed that after extracting from the castle mission along with collecting the doll, I'm in a loop where I'm back in the town, but the game is acting as if it's before starting the castle mission, such as "feeling awkward going up to talk to the boss after just leaving", and "Finished chatting with the two co-workers about the castle".
When the game puts me into the mission, I start at the second checkpoint near the castle and playground, and talking to the co-worker sends me back to the town, starting me in a loop.
Fun game so far though, I liked scenes like the pink slime monster. ^^ Hope there are more scenes with monster entities, not gonna lie I was assuming the possessed armor in the castle bathroom was gonna be another scene. XD
