> These games are the starting point, but the bulk of the game is new puzzles combining mechanics from different games together
Seems like the puzzles are novel, but the mechanics are not?
The basic mechanics look like very standard type of puzzle mechanics (e.g. Sokoban) that have been in many games over decades.
interactions between the various mechanics in the games likely yield countless surprises, and let you build something considerably more elaborate than thesum of its parts..
With Blow the devil is simultaneously in the details and at the meta level.
For example in the Witness, which I consider one of the best puzzle games ever made, you get a fairly simple core mechanic, but the game builds upon it in very interesting ways. It feels like a journey of learning and always challenges you in some novel way at each step. There are also several revelations along the way, where you discover new layers on top of the core puzzles.
I would expect that this new game will feature similarly careful design.
