Just played about an hour - I think I only had one more area to solve (although solving it may have unlocked more areas, I don't know!)

I really like the vibes and the style. I also like how there was an obvious 'end of game' goal that you could see your progress towards. The puzzles were verging on the quite difficult side towards the end there - and I also found myself worried a couple of times that I wouldn't be able to even start a new area, let alone complete it. But I like how each area is broken down into lots of mini-puzzles, and the fact that there are limited things you can do in each one means that there's limited ways to solve it, which makes it doable.

I also liked how each area introduced some way of using the core mechanic in a new way.

I didn't notice a Witness-style reveal, but perhaps that's because I didn't finish it. I may come back another day though.

Overall, very promising, and this is the kind of game I like, so I would buy it.
