When a Brawl Begins, you can switch between your 3 brawlers using the Space Bar. Thrower - Aim with the mouse pointer, and click to throw. Builder - Click the Plus button. Creator - Click a certain size of snowball you want. You win by depleting your Opponent's Health. You can click the Resign Button if you think you're cooked half way through a battle. You earn XP through achievements, then you can use that XP to upgrade your stats, improving your ability to Brawl.
I made this project by using my Brain. Balloon Mode coming soon! If you have any further questions on how to play, just comment!
