Thermomorphs Game Description
Duel as a squishy elemental slime on a beat-driven board. Each one-second beat you queue two actions, then every slime moves at once, so outguessing your rival matters most. Heat up, cool down, harden or soften to shift between Slime, Water, Gas, Stone, Ice and Magma, or push to extremes like Plasma and Ghost. Play 1v1, Best of 3, 2v2 with an AI ally or a four-slime free-for-all across five arenas.
Know Your Forms
Temperature and hardness each run from -100 to +100 and together decide your form. Water and Gas can move two cells per beat. Critical forms hit 1.5x harder, but very hot slimes lose HP every beat. A plain Slime's Goo Spit breaks critical forms, so staying neutral can be a smart counter.
Modes and Arenas
Fight a 1v1 duel, a Best of 3 series, a 2v2 with an AI teammate or a four-slime free-for-all, or sit back and watch AI vs AI. Choose one of five arenas, set the AI to Easy, Normal or Hard, and enable Slow Start while you learn. The music is generated live and follows the beat.
How to play Thermomorphs?
New players can start with the short interactive tutorial. Every beat, fill your two action slots, then all slimes act together when the ring empties.
Keyboard: arrows move, Q attacks, W fires a magic bolt, E hardens, R softens, two opposite arrows cast form magic, R then an arrow dashes, Backspace or Esc clears slots.
Touch: use the on-screen pad and buttons. Change temperature and hardness to pick the right form, and knock out your rival or lead on HP after 180 beats.
