Field of Thorns

A pixel-art tower defense game. Grow a maze of thorns to steer the slimes, build towers, pick bonus cards and hold the gate for 30 rounds.

• Story campaign: one big land, conquer the Slime King's camps and free the Queen
• Challenge mode: 5 difficulties with 40 maps in total, unlocked as you clear them
• 9 towers plus Gold Market and upgradable Thorns, each up to level 10
• Bonus cards with 10 levels and milestone bonuses
• Plays with mouse and keyboard, or on tablets and phones in landscape

The whole game is a single static index.html — no build step. Deployed on Vercel straight from this repo.

Setup on Vercel

• Static game: index.html, plus manifest.webmanifest, sw.js and icons/ so it can be installed to a phone home screen and played offline.
• Shared ranking: api/scores.js (a Vercel serverless function). Connect an Upstash Redis store from the Vercel Marketplace to this project (Storage tab); it adds KV_REST_API_URL and KV_REST_API_TOKEN. Redeploy afterwards. Without it the game still runs and keeps personal rankings in the browser.
