    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.

Crossy Box: Traffic Tourist

I wanted a new seed for the next level but I only had space for P++. Fortunately we can do P++ on every iteration of the loop, until Boxy gets hit by an invisible car on row 0.
u/joeytwiddle

(Actually around 6 chars could be saved if we scale the canvas down, like MrM@_S did in his remix.)
u/MrM@_S

Replacing rectangles with 🚗s also saves bytes.
u/joeytwiddle

I can get 🚗 and 🐸 in ... 141 bytes ;)
u/joeytwiddle

Correction: The scene changes when Boxy get hit by the last car in row 1. Cars in row 0 do not re-assign X (and do not move).

This is awesome :D A game in 139 bytes, and I actually enjoyed playing it!

You could keep it as +' |' instead of +<return>| but hey, we want to see the whole thing, right? :D

Challenge: Add occasional mistakes like skipped characters / typos etc.
u/Polyducks

I'm struggling to understand how this works. Where have you got the function input from? Amazingly realistic!
u/Jenky

It's from (u+'') - afaik, it's basically a short/cheat way of converting anything to a string in JS :D
u/Jenky

Also, down to 119 and whole string within canvas - https://www.dwitter.net/d/2524

u/Jenky

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522
u/donbright

:o
u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!

just replace 𝘼𝙋𝙀𝙍𝙏𝙐𝙍𝙀 with Aperture. Which also is a bit heavy on the byte count.
