Enemy No. 1 is a twin-stick action roguelite set on the number line. It takes its escalating runs from Risk of Rain and its eat, grow and split mechanics from agar.io.
Your number is your health, your size and your damage. Shoot numbers, collect what they drop and watch your number climb. A bigger number hits harder and has more to lose.
You have 1 problem
Numero Uno, in his attempt to become | Absolute |, has caged Zero and corrupted every number with a 1 in it. Get to him, free Zero and put the number line back in balance.
Every pickup changes your number, and any part of you with a 1 in it stops healing.
Split for firepower. Merge to survive.
You are a cluster of nodes, and your primary weapon fires from every one of them. Split and you have more guns on smaller, more fragile bodies. Merge back up when you need to take a hit.
It is also how you deal with a 1. 100 splits into a 55 and a 45, and both of them heal and shoot.
The clock is not on your side
The swarm grows with every minute you spend and every stage you clear. Each stage takes you closer to defeating Numero Uno. Alternatively, continue playing the game in endless mode to challenge yourself against the clock.
A different number every run
55+ stacking pickups
In four rarities. Chain Rule arcs lightning between enemies. Corollary turns kills into homing darts. Inverse Function brings you back from the dead, once.
Weapons of Math Destruction
