This was pretty fun! The mechanic feels really fresh and I think it has a lot of potential. I liked the puzzly thinking combined with timing challenges.
My main complaint (like some other commenters here) is that it's quite slow, and on many of the early levels I knew what I had to do but had to wait ~10-15 seconds. But other than that, I think you did a great job, and I only wish there were more mechanics/levels.
