I have to confess, I did not beat the last level before rating, but I have to get back to it to figure that one out.
Seriously though, really nice puzzle game. Had to unlock the last level before I could put this away.
Nice variation of challenges, and nothing felt repeated, nice and simple mechanics to understand.
Star system made me want to try again to improve, and figure out that one "smart" solution.
The music was nice, but had to mute it after 3rd level, as it was too repetitive for me.
Took some time at the start to understand that the arrows ware actual arrows.
Great job!
