I adore Picross and this game was such a treat. In fact, this may well be the best homebrew I've ever played; it's really well made and feels like a complete package of the same calibre of any big studio GBC release of that era.
Thoroughly enjoyed getting to 202% (took me ~10h). The setting, story and friendly vibes make this such a nice game to wind down with. The simple adventure feel paired with Picross goes so well and I would be very excited if a sequel was ever released.
I also absolutely loved the chiptune versions of the various classical pieces, was a very pleasant surprise to come across some of my favourites as I was playing.
