It is a very fun game, with well-done puzzles, the one I liked the most was door 7, I had that "aha!" moment because the solution was in plain sight, but I didn't see it, and I really liked the movement, this time it feels more fluid and less heavy, like a platformer game, I hope the full game will have equally amazing and fun puzzles.
And I have to admit this, I don't like puzzle games that much, obviously I've played some as portal, which I liked a lot, but generally I don't like them that much because they seem difficult to me and I stop playing them, instead, your game has some puzzles that make me think about what the solution could be, but not making me stay days or weeks without playing the game because the puzzles are very difficult.
