This is really impressive! The mechanics here are simple at first glance, but give way to a lot of depth. None of the levels felt superfluous, which isn’t often the case in puzzle games made for jams (at least in my experience). The game is extremely polished, too: the controls feel great, and the graphics are clean. The only issue I had was that occasionally some countdown lengths felt like they needed to be fine-tuned somewhat, with me having to wait a second longer than what felt natural or whatnot. That kind of thing isn’t objective anyway, though. Great work on this.
