Metatherm [Thermodynamics Weaponized]
You are a practicioner of metathermics, a dynamic setup playstyle featuring unique interactions between their own projectiles, with capabilities augmented by their running "temperature".
Just so happens you are also a ratfolk. Aka, 32 pixels of condensed bastard.
tl;dr: hit the purple with hot/cold, learn from there
advanced explanation
Your primary strategy: chuck stuff out, prepare a setup, and watch what happens when you burn, freeze, or "conduct" it in the face of an enemy.
Your secondary strategy: manage your temperature to not explode, increase damage of your attacks, and use cold to build up "ice armor"
Your tertiary strategy: explode violently because you punched an open flame with a fistfull of "thermoconductive fluid."
Your quaterinary strategy: explode violently because you decided it’d be a great way to use a "cold" attack to draw in more heat when already "hyperthermic"
Your quinterinary strategy: explode, but cutely.
The path of the metatherm is by no means an easy one, and will require practice and experimentation to master.
But in doing so, you will become a literal force of nature, bending the laws of physics to lay waste to your foes.
Stay icy-hot, be patient, and learn to revel in self-destructive chaos as you unleash the fury thermodynamic discord.
Basic ideas:
Project purple ‘conductive’ mist/bolt attacks and use heat to detonate them in an explosion or cold to freeze them to deadly icicles.
Enhance your defenses with "Ice armor," allowing you precious turns to set up for attacks
Manipulate the temperature of the air to create powerful wind funnels and drafts to both navigate the stage and manipulate the trajectory of projectiles. You can even use "Super airblast" to send a sparkbomb right at its caster.
Take advantage of the interactions between your projectiles and temperature to create unique, with differentials creating unique effects ranging from small explosions to opponent-drawing vortices.
Create "Stasis Drafts" to freeze your own projectiles in place, creating a space to prepare your barrage of icicles or a deadly trap explosive gas waiting for you to set off. (or just let your foe run into some fireballs..)
