Man, you sound like you’re just using random words you heard in class. Clearly you have no clue how user registration actually works, let alone backend development.
You basically have to restore a wasteland back to lush, green nature.
Much like a city builder, this is achieved by putting down buildings. The twist is that at the end, you can’t leave a trace so you need to demolish everything again.
It’s not a long game, but I thought it was very satisfying. A relaxing puzzle/city builder with soothing music.
