Lymbus

Descend into a digital labyrinth of our own making. Move around with your keys. Do everything else with your cards. Exercise maximum strategy in building your deck, then throw it out the window in screen-shaking, bullet hell-style battles. Combat happens in real time, meaning every moment matters.

The year is 19XX. Great strides in neuromechanical research have allowed the most common human actions to be transcribed onto memory cards. Great oversights in said research have also made it so nobody remembered to save a backup. After a catastrophic crash renders most of the population comatose, you are tasked with diving into humanity's collective unconscious to retrieve the memories that may hold the key to ending the blackout.
