Wow, this is a stunning entry ! The visuals are great and the animations are on point. The game loop is very interesting, you are only compelled to play over and over again thanks to your own curiosity and will to experiment, which is great. No pressure, very relaxing concept, i love it ! It also perfectly fits the theme.
There's just one thing I didn't like, and that is the fact that if you want to cancel a tile, you have to click on the red cross above. You can't just click on another tile ; in this case, the UI is blocking. That's a pity. And maybe make a smoother animations, with an easing curve, to move the camera when you click on a tile.
This is an absolutely GREAT entry, I'll surely keep it and try again later to get all 31 tiles. Awesome work !
