You get 10 seconds of 'life', enemies and bullets drain this when hurting you (by touching you), multiple enemies/bullets touching at once drains quicker, and when your life runs out the game ends!

The goal is to survive the endless amount of enemies (5 per second) for as long as possible, for bragging rights and what-not.

There are 5 types of enemies:
Normal: these follow you
Lunger: these follow you with large quick jumps
Sniper: these stay still and fire at you instead
Dodger: these dodge bullets, using a very basic method
Mine: these are bigger, do not move, and explode into bullets when killed

There are 9 spawn modes:
Normal: 60% normal, 10% others
Less Specials: 80% normal, 5% others
Swarm: only normal
Lungers: only lungers
Bullet Hell: only turrets
Mine Hell: only mines
No Mines: 70% normal, 10% others, no mines
No Bullets: 70% normal, 15% others, no mines or turrets
Super Swarm: only normal, 2x spawn rate

When you kill an enemy, there's a 3% chance it drops a powerup. You can collect the same powerup multiple times to have it last longer than normal as it adds to a timer for it.

There are 5 powerups:
Shield[70%]: Blocks all damage for 2 second
Pierce[10%]: Shots you have fired pierce for 4 seconds
Regen[7%]: Adds 1 second to your time remaining
Homing[10%]: Newly fired shots will home in on enemies for 3 seconds
Wipe-out[3%]: All enemies are killed for 0.4 seconds
