    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Click on the canvas to move the square. It keeps its velocity when it moves, which leads to some interesting orbits

I made it better

Click the canvas, then tap any key to start. Move your mouse to keep the ball in the air.

This is great

Cookie clicker! Click for cookies, press space for clickers (each one costs 50 more than the last)

Show more comments…
u/KilledByAPixel

awesome! i was confused at first, you need to click 50 times before you can click space to buy an auto clicker.
u/katkip

Awesome!
u/lionleaf

Awesome! Pressing space scrolls the page down though :(
u/lionleaf

I've spent way too much time on the original cookie-clicker... I'd also recommend the paperclips game

u/mildlybean

I love the paperclips game
u/katkip

tycoons are boring and fun in the same time
u/lionleaf

I got to 600M cookies and now have 7k clickers. Turns out at some point it starts becoming possible to go negative as well. Currently at -130M #cookie #cookie_clicker
u/awareness481

You have 2 characters left. You can use those to cover any number overflows :P

Nice one. Can use this to demonstrate that JS uses the client's local environment clock
