A superbly-designed set of three-dimensional sokoban puzzles, wherein you must flip, turn, and nudge pipe parts into completed aquatic routes, while allowing your player character to still exit the vicinity without ruining anything. If I can nitpick, the arrangement of the puzzles does not follow a typical difficulty curve at all - in many cases the new mechanics and gimmicks introduced in the later stages (and more heavily featured in the "Hard" and "Expert" stages) were easier to comprehend than the basics of flipping and rotating those pipes in tight spaces.

Pipe Push Paradise also appears to be shooting for something a la A Good Snowman... with its closed-garden-open-world design, but outside of the very satisfying finale, it's not really explored. The strict tropexotica theming is also pretty passe, and talking to folks is usually completely uneventful. In general a feeling of progress beyond the completion ratio increasing was sorely lacking. My final solved puzzles before the (wonderful!) conclusion were in "worlds" 4 and 2 of 5, respectively.

These minor confusions compound to detract from an otherwise extremely challenging and rewarding traditional puzzler.
