Basically if you were to add yourself you must do a few things: remix the project (obviously) duplicate an character. I would say Char1 is a good base add an variable with your ocs initals. (this is important so the code isnt broken) change the ms variable to your ocs initals. when the thing starts make sure its variables value is 1, so we know its alive. when it dies make its variable 0 change the winnning code to make sure if your ocs initals are still in and if the ppl left are only 1, then it triggers the win message last. change the costumes!
