Pretty fun! I liked the springy-ness of the characters, it felt really good to swing them across the levels, but I got kinda bogged down when the spikes came out. The way they kept resetting just a bit behind where I was last stable and the fact that they didn't reset in a "sticky" state made it kinda frustrating to get back to where I was.
I finally got hard-stopped at the first button/door area because the blue guy got through the door and the red guy got caught on the spikes. The door came down, the blobs reset, and it was impossible for me to move forward because the crate was juuuuust too far away to reach. Maybe just keep doors that have been opened up?
