Thank you Mousemysak. This is related to lack of instructions, which I totally forgot. The idea was "delaying the camera zoom between the targets creation + play time", so the player has some seconds to see the point A and B, but as this is a prototype there is many more ideas I can come with. So far I feel the gameplay is a bit repetitive and lack of fun after some minutes playing. But I hope I did a good job as my first jam.
