As I write this review, I am in the process of playing and have reached a dead-end. Unable to progress, I will write about what I have seen thus far.
As a point-and-click, the game leaves me wanting. Part of the success of these kinds of games is the story that the player is given to motivate them to keep working to solve the puzzles and find what needs to be found to move on. I do understand that this is a dream of yours, or of someone you know, however presenting the dream as is to players who did not experience it as you have does not make for a compelling game. The effect would have been stronger with a bit of story or something... substance to sink our teeth into. The idea not to label anything is one I understand... where is the mystery in that? However, being thrown into this game with nothing at all, no information except for the description you wrote for it, is jarring in a bad way. The further I got, the less I felt drawn into a mystery and the more frustrated I became pixel-hunting on every screen. A game made entirely of pixel-hunting is a little tiresome after a while, especially when I can only interact with things necessary to drag the game forward on its slow march to completion.
That being said, I like the music and the simple art style of the game. It feels like a construction of the brain, creating things half-way in some places, and other times rendering a lot of detail. I like that mostly everything in the Pre-School is a sticker on the wall.
As for navigation, I think arrows would have been good. There are certain things you must give up when turning something into a game; the feeling of not knowing where you are going is often one of them. As I sit here stuck, I can't help but think I am missing a location or something, and without a mini-map or arrow navigation, I have no way of knowing.
In conclusion, this game tries to capture a big idea in a form that is far too minimalistic. I don't think I will finish it, because I have looked everywhere for a way forward and can find nothing. I think if you refined this game into something polished and truly complete, it would be wildly successful.
