Toy Box Tower Defense: Game Design Doc

A Tower Defense game set in a Toy Box world focused on Vehicle Customization, where NPCs remember what you did.

Core loop

Place and upgrade towers to survive waves, earn coins, then use them to unlock new towers built around vehicle customization for harder maps.

Monetization plan (suggested prices)

• Commander VIP Badge: R$249–499
• Faster Reload Speed: R$99–299
• Auto-Upgrade System: R$249–599
• Wave Skip (1 match): R$15–35
• Coin Pack: R$25–199
• Starting Cash Boost (1 match): R$25–49

Retention hook

Weekly challenge map with modifiers, plus a visible progress bar toward the next big unlock.

Scope

Team project. Big enough that a small team, or a few months solo, is realistic. Cut hard to ship a first version. Why: vehicle customization needs extra systems (saving, UI, and balancing); the twist ("where NPCs remember what you did") is technically tricky.
