Simple logical "connect dots" game. The energy resource is nice addition. It could use more challenging levels.
Kudos for the background music. At the first glance it sounds as someone is learning to play musical instrument, but actually the structure is pretty good and interesting (maybe because there is not one constant rythm and the pauses are all different lengths) and it definitely fits the mood of the game.
P.S.: When I was looking at this game on smartphone, this game was the only game from this jam not marked as smartphone incompatible, yet the tutorial threw me the curveball with right mouse click. :D
