Very cute Lemmings-esque game! I enjoyed the crayon aesthetic a lot. The sheep outfits/designs were also cute.
I liked the music, but unfortunately something happened and the main level theme didn't loop. This happened pretty early, so I wasn't hearing music for most of the time I was playing.
The sheep behave interestingly at ledges. A sheep will start sliding down a ledge, but since it's still "grounded", the sheep can still jump. Kind of like pseudo-coyote time. This was really cool, however, turning around did not have the same interaction at ledges which felt inconsistent.
Some thoughts on particular levels:
The one where you use the mouse to move platforms on a path. Unfortunately, the speed at which people move their cursor, even if it's very slight, is inconsistent. This results in seemingly inconsistent physics behavior from the player's perspective. I may only move my cursor slightly, but this still creates a strong "force" which propels the sheep upward. (At least I assume that's what's happening.) To be clear, though, I use a trackball mouse. Which probably makes this more noticeable since one is able to move their whole mouse with their hand/wrist more consistently than moving a trackball.
There's also the level with the two large moving platforms that go right to left. Outside of the fact that moving platforms are hard to program, the main thing I wanted to point out here is that you can't jump straight off of the first moving platform onto the right ledge without breaking the sheep. Which means you kinda have to make the sheep jump onto the edge of the moving platform and then have it walk off as it moves away. This didn't feel intended.
Since this is primarily a mouse game, I think it would've been better to be able to pause/retry with a button on the screen that can be clicked. Esc is the only key that's necessary to play, so it would've been more convenient for it to be accessible with the mouse.
I liked that jumping was slightly faster than walking, but jumping has risks since it's a long, fixed distance. It created a fun risk-reward.
