Spawning Ground

Part of Confounding Calendar 2022 (https://confoundingcalendar.itch.io/)

Normal sudoku  sokoban rules apply.

Goal: Collect all the collectable thingies (gems? flowers? mini-polyominoes? you decide!) to win. The number of collectable thingies on a platform indicates my personal recommendation for solve path (working in order from least-to-greatest thingies): the solutions logically build on each other and the last one is quite tricky! But ymmv, so feel free to solve in whatever order you'd like.

Hard mode: even if the 4-thingie and 5-thingie platforms were both 1 block shorter, it would still be possible to win.
