probably one of the worst picross games available on the 3ds. the fact that progression is gated by both energy and picrites, both time-dependant resources (and picrites make you grind for them), really saps out any fun out of playing multiple puzzles in a single session. each puzzle features different goals that you must beat in order to get extra picrites, with some of them being as ridiculous as asking you to carry a specific pokémon that you won't be able to unlock until multiple stages later, or beating a 20x15 puzzle in under 6 minutes which is only feasibly possible by cheesing it with multiple legendary pokémon skills or by straight up looking up the solution online. the most fun aspect out of these games, micross (a massive illustration made out of multiple 10x10 smaller picross puzzles put together) is also gated behind these goals since you must unlock every single smaller puzzle (a tile) through this method.
gameplay is just like all the other 3ds picross games made by jupiter and its OST is as bland as it gets. also this is subjective but the actual pixel art you get out of these puzzles is pretty ugly, with some really putting in the effort to portray a pokémon as a 10x10 sprite.
there's basically no reason to play this before any of the many other picross games on the 3ds unless you like pokémon that much that you're willing to tolerate multiple f2p mechanics hindering your progress at every single roadstop, in which case not even arceus can help you.
