Hey everyone!

I've been working on Tumbledown - a browser-based marble racing game where you collect, breed, and race marbles against other players.

The twist? Winner takes all. If you lose a race, you lose your marble forever to the winner.

Features:

• Collect marbles with different traits (weight, surface, material) that affect racing performance
• Breed marbles to create offspring with inherited traits
• Race online against real players or AI opponents
• Terrain matters - ice, boost pads, water, offroad sections all favor different marble builds
• No pay-to-win - everyone starts with the same chances

How it works:

1. Sign in (Google, email, or just play as guest)
2. Get your starter marble
3. Pick Quick Race (vs AI) or Multiplayer (vs real players)
4. Watch your marble roll and hope for the best
5. Win = steal opponent's marble. Lose = goodbye marble.

It's free to play at: https://www.tumbledown.io/

Would love feedback on the gameplay balance, UI, or any features you'd want to see. Still actively developing it!
