Problems with creating checkpoints in my game.

Hey everyone,

I am in desperate need of help here, my game is nearly complete. You play as 3 protagonists trying to escape a prison by following instructions. The only issue i am having is creating checkpoints in my game.

The frame called Prison Cells is the entire gameplay so ignore everything else. I chose to make it all in one frame on purpose :).

Really dont know how to incorporate checkpoints in my game, i want them after each level is completed; Levels 1.1, 1.2, 1.3, 2.1, 2.2, 2.3.

My game is too big to upload so i just shared it via google drive.

Anyone would be amazing! Thank you in advance :)

Kind Regards,
Kieren
