Ok, so I've implemented the checkpoint system with an event observer in the game over screen which leads to the reward video to continue. However, I can't seem to find a way to make this only occur once per try so the player can't use checkpoints in the game try infinitely. This leads to when a player dies they are given the ability to resume their game after watching an ad, which works as intended, but when the player dies after watching the ad, they are given another opportunity to watch an ad which can go on forever, my goal is to have this only allow one death to be continued. I am using BB Version 2.3.5. Please help, and see my Game Mind Map image below.
