WHY INSTANT WEB GAMES WIN
Legacy studios burn over \$1,000,000 and 18 months before discovering if a game is fun. We build for the explosive new wave of frictionless web discovery with instant player feedback.
The Instant Web Advantage
Zero-Install Friction
Players click one link on YouTube Playables, CrazyGames, Poki, or Discord and start playing in 2 seconds. No 200MB app store downloads.
10x Production Velocity
One software architect leverages specialized AI workflows for 3D modeling, physics tuning, and level design — shipping in weeks instead of quarters.
Day-1 Organic Discovery
Direct access to over 1.1 billion web gamers across established portals without unsustainable \$5+ mobile app store acquisition costs.
Engineered For Retention
Our games aren't tech demos. They feature proven retention and monetization loops built directly into the core gameplay:
OUR PRODUCTION PIPELINE
From initial concept to gold-master release in 21 days:
3D Asset Synthesis
Concept to low-poly stylized models in Blender & Three.js with runtime GLB material optimization.
Gameplay & Physics
TypeScript mechanics: responsive vacuum foliage suction, 2D compass guide, CrazyGames SDK v3 integration.
50k Bot Playtesting
Headless automated agents simulate thousands of playthroughs to balance upgrade curves and Lucky Wheel retention.
Instant Web Release
Global 0MB distribution across YouTube Playables, CrazyGames, Poki, and itch.io with zero install friction.
CLEAN LEAVES 3D
Our flagship game: a cozy, satisfying 3D cleanup simulator built in just 3 weeks with our AI-native production pipeline.
Satisfying Core Loop, Deep Metagame
Foliage Physics & Compass Guide
Sweep and collect autumn leaves. The 3D backpack expands in real time, and a directional 2D compass guides the player to the nearest selling trashcan.
Cash, Diamonds & Rebirth Tiers
Upgrade collection radius, speed, leaf blowers, and autonomous mowers with Cash. Collect Diamonds for prestige skins and multi-tier Rebirth multipliers.
LiveOps Retention Loops
5-minute Lucky Wheel with confetti physics, 2-minute tiered Free Gifts, and spontaneous 2x Cash and magnet rain events.

HI, I'M LENNART.
“I build joyful, instant 3D games by combining solid software engineering with modern AI workflows. No corporate bureaucracy — just great gameplay delivered to players in seconds.”
I am a 3D WebGL developer and software architect based in Germany. With Clean Leaves 3D, I proved that an indie developer leveraging modern AI tooling can design, engineer, and ship a commercially viable 3D game in 3 weeks. lennart.lol is currently raising Pre-Seed funding to scale this studio model to 12 titles per year.
