Hi Stumbler! Inferno Dragon here to assist you with any gameplay & feature related FAQ. 🐲 
    
Here in the Customize sub-menu, you’ll be able to design your own character using what you’ve unlocked so far. Ms. Stumble and yours truly are available by default. Though, there are many unique skins which you’ll have the chance to unlock as you continue play the game.   

Aside from skins, skin tone is also customizable using the list of options. These range from normal human skin tones to alien and monster-like skin tones. Feel free to experiment!
 
While there’s no in-game chat, emotes can be used during a game. These can range from light-hearted banter to taunt animations.
 
Traditional Special Emotes have been transformed into Abilities! Just like Special Emotes, players can equip Abilities and use them during matches, which can directly affect their chances of winning.

Several victory animations are also available for you to express yourself and even gloat at eliminated players in-between rounds.

Lastly, footsteps leave a unique trail behind your character while running around maps.

Have a scorching day!
