Thank you for playing my game. I only had an alternate route for the player during the tutorial boss fight. I feel I should have elaborated more on the main mechanic in the instructions and also show how to make use of the arrows on the floor, if you shoot in the same direction as the arrows the shape will hit the pool (even if the pool is off screen) and the exchanged shape will be passed back to you. In the first main boss (one that just goes left and right), if you shoot a triangle towards the square pool, the returning projectile will hit the boss from behind, without you having to bypass him.
