Buns & Cream - Food Delivery Racing Android Game (Kotlin + Jetpack Compose, 1000 Levels, Traffic, AdMob, In-App Purchases)

Buns & Cream - a complete food delivery racing game for Android

Buns & Cream is a ready-to-publish delivery game written in Kotlin with Jetpack Compose. Players pack a bakery order, then ride a scooter through a pseudo-3D city street to deliver it before the time runs out. It targets API 36, ships with 1000 levels, road rules (school crossings, police speed checks, roadworks), AdMob with Google consent and Google Play Billing. Open it in Android Studio, change the name, IDs and artwork, and publish.

Step 1: pack the order

The order card lists the foods; every tap on the counter counts live. Wrong foods cost time, a quick pack earns a bonus. Eight bakery foods unlock over the levels, with decoys and shuffled counters later on.

Step 2: beat the traffic

A pseudo-3D street with buildings, trees and lamps. Three lanes go the rider's way and one carries oncoming traffic. Cars change lanes with blinking indicators, buses and trucks join from level 5, and other drivers honk. Swipe to change lanes, hold the gas pedal to boost, brake in time and use the horn.

Road rules: ride safe or pay

• Police speed checks: a speedometer and limit sign; riding too fast brings the officer with a coin fine
• School crossings: the signal turns red and children cross; running the red light costs coins
• Roadworks: cones and barriers close a lane, hit cones fly away

1000 levels, more stops, longer roads

A vector city map shows every route in km. Levels grow from 0.7 to 2.4 km with up to three stops and denser, faster traffic. An automated test rides all 1000 levels without a crash or a fine, so every level can be finished.

Scooters, boxes and upgrades

Four scooters with real top speeds, three delivery boxes with bonus seconds and bigger tips, and upgrades for engine, handling, coin magnet and helmet.

Monetization built in

AdMob banner (menus), interstitial (every 2 levels) and rewarded ads with the Google User Messaging Platform consent flow. Rewarded videos give +20 seconds, an extra heart or free coins. Play Billing 9.1 for coin packs and Remove Ads.
