This is such a clever twist to the "organized neatly" formula! Having to cater to the requirements of each block adds another layer of challenge to the classic block placing puzzle. Love the visual style of the blocks. Its simplistic, poppy and clean, and the whole ambience goes perfectly with the poppy music.
Just a small QOL suggestion, maybe provide a way to view the block's condition after placing it? Or have a list of requirements as a table on the side so that I can see it from a glance instead of having to remove the piece and mouseover to view them.
Thanks for participating!
