MAINLINE
You are caffeine: kill to refill a 4-second timer
by Bakuevo
Summary
You play as caffeine injected into a vein, shooting through six chapters of bloodstream toward the brain before metabolism ends you. Your survival timer starts at 4 seconds and only refills through kills, while each kill raises your movement speed and weak-point finishers reload your single gun.
- 4-second survival timer, no visible bar
- One gun per run, card upgrades stack across swaps
- Normal, EX1, EX2 and Endless modes; 1-3 hours
