Apricity

Apricity is a top-down shooter designed to be played with friends. 
Heat System
When you deal damage, you build Heat, and at 100% Heat you become HOT, increasing your attack speed. After a few seconds of not dealing damage, your Heat drops to 0 almost instantly. Reloading (reloading is just the term for a special action, you can fire your primary weapon infinitely) conserves Heat and recharges your abilities, unless you are injured, in which case your Heat is expended to rapidly heal you.
Importantly, enemies drop orbs on death that heal you and recharge your abilities, often forcing players into a choice: do I back off and reload, or just keep shooting and hope I can heal from the orb?
Classes
Apricity has 11 character classes. Each class has a different weapon, passive, and two activated abilities.
Classes interact with each enemy type and item differently, and each class has a special relationship with the Heat system.
Gamemodes
Apricity has two gamemodes. The first is Adventure, in which players make choices in a text adventure in between combats. Winning combats equals success in the text adventure. The ultimate goal is to destroy Catrapos.
The second is Endless, a simple but fun score attack mode that appeals more to singleplayer users.
