I played the whole game and I like it. It's not very creative but visuals and sound are fit each other. But heart system is useless though because all it does reset level, but so can the player. Most of the time you have time to pre-place objects so it's whether player place something wrong and have to reset(he can do it by himself), or he place right and doesn't lose a heart. So it would be better just get rid of hearts or get rid of time for pre-placing objects.
