This is my first experience attempting picross, so it took me a little while before I clicked how these things work- I really felt like Cassia as I went through things haha; (though no fault of the game itself, the tutorial explained things just fine!) I ended up really enjoying it! Making mini pictures to progress was really fun!
I mean this as high praise- this feels a little like some small nintendo DS puzzle title with adorable graphics I'd have played as a kid and still feel nostalgic for ♥ Such a cute game!
I think it kinda goes without saying, but the Ren'Py usage is so impressive, I'm certainly inspired- so yeah, fantastic job, I loved it!!
