Summary: Recommended. Review: This unique puzzle game with an amusing story is an achievement hunter's dream that may also appeal to fans of the adventure genre.

+Stacking is best for puzzle or adventure gamers. The game world is full of stacking dolls as people, which provides unique gameplay for capturing other dolls and then sometimes gaining their abilities.  All that is used to accomplish objectives/goals or hijinx.

+Main story and side stories are well crafted and engaging for me, building a weird world full of stacking dolls.  The game could've been longer at 6 hours for me. This game can be an open ended challenge, or it can be really simple using the game's copious notes, hints, and in-game guide to find where objectives are.  Art & music is perfect for the setting and premise of the game.

?There are not only Steam achievements, but in-game achievements are rampant with at least dozens per area/level. Also, each one can be returned to at any time after the main goals for that area are completed.

-Characters are simple: They cannot jump, run, or have items unless related to their special ability or a special event. Given the amount of in-game help provided, the devs could've made such mechanics work without degrading gameplay, but it may have taken much longer for the game to be released.
