How do I

I have linked all of my levels to a single event sheet which functions as the engine for the game. However, the events I have nested inside the 'Every Tick' category only work in the first level. Does anybody know why that is?

You must have a condition that is not being met mixed in with your every tick category. Try and recreate it in a new project to make sure it is working as you imagined - then, if so go back and check your code with a fine tooth comb and you will find the offender.

Thanks Genki!
