Asymptote

You are x. Worth exactly one.

Asymptote is a fast 2D math platformer. Every number in the room is an enemy, and your only weapon is yourself: throw your own value, and each hit subtracts x from whatever it touches. Grab operator orbs to grow, and climb from 1 to Ten, Thousand, Trillion, Googol... past every number there is, all the way to ∞.

Features

• Grow your x with orbs: +k, ×2, x², √x, −x, and ×i, which turns the whole room a quarter turn.
• Trig orb: a unit circle spins around you. sin throws weave through everything, cos throws come back like boomerangs, and tan throws ride the tan curve up toward its asymptote, growing as they go.
• f(x) gun: aim with the mouse and fire straight lines, f(x) = mx + b. A line hits every number on it.
• Numbers that fight back: negative numbers need the right sign, sin numbers swing between + and −, square numbers throw dashes, and ÷0 black holes pull you in and drain your power.
• ∞ bosses: only ∞ can break ∞. Keep squaring until x overflows.
• Endless rooms, three difficulties, dark mode and gamepad support.
• Optimized to run on low-end laptops with integrated graphics.
