User Summary
Pushmo (alternately titled Pull-blox in the UK and Hisa-Osa in Japan) is a semi-platforming puzzle game
In the game, you control Mallo, who has volunteered to help the builder/caretaker of Pushmo Park to rescue a number of children who've gotten trapped inside the various Pushmo puzzles in the park, thanks to a mischievous boy who keeps resetting the puzzles while they're playing on them.
You do this by pulling out and pushing in blocks so that you can jump and climb up the puzzle to the top where the children are stuck.
