Complete 2D Game Design

I’m developing a 2D mobile game where the fun comes from playing. What I need now is the full design foundation: a clear set of rules, a rewarding progression loop, and the systems that turn simple taps into long-term engagement. Here’s what I’m looking for you to deliver: • A concise Game Design Document detailing core mechanics, economy, level flow, and reward structure. • Wire-framed screens that map every menu, HUD element, and in-game prompt so developers can plug straight into production. • A first-pass content plan outlining characters, items, buildings, and how they unlock or upgrade over time. If you’ve shipped 2D builder, management, or collection titles before, I’d love to see examples. Let’s craft a tight, scalable design that keeps players coming back day after day.
