Picross is based. This is a very solid version of picross and the start of Jupiter's e series on 3ds. Has a nice, simple aesthetic and it controls really well, but is strangely missing features such as row/column counter, highlighting tiles, bgm change, and some other miscellaneous visual settings. This is weird considering Jupiter's picross game on ds had several of these things. On the topic of the puzzles themselves, they're very solid, but my one gripe would be that their difficulty seems to oscillate between fairly easy and extremely difficult within level sets. Overall very standard picross experience. Should have more stuff but this should be a good baseline for any picross game. Highly recommended if you love the genre.
