This is great! I absolutely love the idea, it's very creative to mash this type of puzzle game together with the time limit and the river-crossing part. It has a very cohesive feel, and the time limit felt really well-tuned to me. On my second attempt, I just made it with 5 seconds to go. I probably could get faster at it, but it was thrilling to get it in just under the time limit. Amazing work, this is a great idea with great execution!
