"Chemical Odyssey" is an action-adventure game where you play as an alchemist on a dangerous journey. You have no swords, guns or magic, only potions that you can mix in specific ways to create different attacks, none of which will be useful in all situations. In order to succeed you must think on the fly, use combos and exploit the environment to kill enemies.
The game features 8 unique and handcrafted levels, each with their own unique enemies and music, as well as 2 boss fights.
