I'm building a series of small games where players explore a map and find physical tags leading to different ones. Here's a more detailed explanation, if you're wondering.
I want to push players to 'final game' only after they've played through all the others. I need a simple variable which increases incrementally each time players complete a game which coul be loaded at the end of each. If it's reached a certain value it would trigger a different set of events based on that value. This is all mobile-based, but my understanding is Local Storage saves different keys for each game and I couldn't use it to push data between them for this case.
