Nice little puzzler! I didn’t know how to switch worms at first, but since that wasn’t a required skill for the first few I still had fun until I got stuck (and keyboard mashed until I found the shortcut, I knew the sleeping eye had a purpose!). The puzzle progression felt a little hard at first, but nice and challenging by the end. Overall I had fun, the worm satisfying to move and really cute.
I restarted some of the puzzles because I wasn’t sure if undo was fully working, but I managed to beat all the levels but an early one and the last. Here’s a private upload of the playthrough: https://youtu.be/LG1roMBxXpw
