This may sound silly, but my favorite part was the background! I really liked the cogs moving with the ticking, and it reminded my a little of World of Goo's aesthetic.
As for the game itself, it was fun! Movement felt good and the ability to partially restore the platforms was both a good puzzle element and a good way for players to manage their own difficulty. I do wish you could lock fully-grown platform without having to wait for them to shrink though.
Thanks for the fun game!
