Very cool puzzler. Made my brain hurt and my soul having to sacrifice so many of myself to the cause.
Really good job introducing new mechanics, made the game feel purely difficult from figuring out the right strategy rather than not understanding how things worked. You managed to fit so many levels in without them getting boring or repetitive too, what an effort!
Some of the levels needed so much planning and thought to schedule both your previous and current actions, it gave it an almost assembly line/factory builder feel.
There's really not much to criticize, I think the only little thing that occasionally bugged me was the collisions with walls above your character felt a little harsh. It felt like I should be Y-sorted in front of them and not get blocked by my cap touching it. It only came up a couple of times, but in tight timing situations it meant wasted timmy.
Overall, excellent work, super well designed mechanics and levels, cute timmy. Great entry!
