This was quite the experience!
All the three parts of the game were very interesting on their own.
I loved the intro sequence with the dad, since the dialogues were very catchy and entertaining. And I enjoyed the other extra interactions with the angel and the maid - it was hilarious, more games should have npc interactions like this. The developer story was hitting home, and felt very appropriate to give some context for the events of the game. XD
The puzzle part in the middle of the game was also interesting, even the entire part of finding glitches felt a little hard (and having to remove tile by tile to walk forward, like in the train felt slow), but I liked the puzzles.
While for the last part, it surely went beyond expectations. I liked some of the chases, and the use of the rest area at the end was very clever and unique (even if not clear). Though this part, as mentioned on stream, had a lot of dull moments of walking.
At the end I really enjoyed the game. My only nitpick is that the game has three different sorts of gameplay with a clear cut between them, and you risk driving people away if they like an aspect of the game but not the others.
Here's the saved VOD:
