Hello there, sorry for the grapple not centered perfectly but yeah, i never find solution for this on Construct2 xD
I really love your idea, if i make the hitbox of the swith bigger, we can just grapple the wall and the switch will turn on, but yes missing the switch slow down the action so i will find a solution. Just like the exit button, that's a good idea to change level after the animation.
Thank you for your ideas ! I will fix that :D
