Finally jellied my way to the end! These were a lot of fun :)
35 and, weirdly, 15, were the last to go. I had convinced myself that 15 required some elaborate pushing contraption, so when I finally saw the actual solution, I facepalmed a little bit.
Glad you liked the game! 35 is definitely a tricky one, and 15 is pretty large, so I can see why those were tough.
