This is a very lovely kind of game. Something that is both pretty and zen like. You definitely can feel there was an emphasis on puzzles, but tbh I think focusing on zen would have been much better. It creates a nice gently kind of game to relax with. And then to implement a couple of obstacles/puzzles to keep the game interesting.
I feel like having both an inside/outside is a good game start, but if you want to expand upon this game then maybe more orientations can be required. Maybe add in ways to stop the magnetic/repel each other and this would a most amazing game.
All in all a very lovely and zen like game with a lot of love on aesthetics. Wish there was more then 2 levels to enjoy.
