Super polished and was fun to play! I really enjoyed the way you interact with the fireflies and how you progress by using fireflies as coloured gate switches. Although, I do have a problem with sacrificing my babies! Hopefully they are in firefly heaven... :s
I did feel like I cheated a bit since If I moved my cursor far away quickly the fireflies followed extremely quickly trivialising the timing of the lights slightly. Possibly making them de-select automatically when your cursor is too far away.
I also thought the game could do with additional challenge by making touching the walls remove/hinder the fireflies in some way to increase the amount of precision you need to guide them on the journey to the jar.
