    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

Can you arrange the numbers vertically? Feel free to use the special moves!

It's not a space limitation issue, it's a feature!
u/donbright

absolutley brilliant however e.x/e.y dont seem to work in firefox
u/joeytwiddle

Thanks don. I golfed this over a 24 hour period, but could not squeeze a better "valid move" rule in. Remixes welcome!
u/donbright

firefox should adopt e.x and e.y just so your dweet work
u/joeytwiddle

Hehe. Sadly the mouse coords are also problematic in fullscreen, and on mobile.
u/joeytwiddle

Valid moves are -4,-1,+1,+4. I have found a "valid move" test: **2|17)^17|| Will post the remix sometime.

Classic Slack #loading spinner (RIP release)

u/metamero

cool! also cool it's #compressed using the UTF-16 surrogate pairs method =]
u/joeytwiddle

It sure is! I gave your compressor a try.
u/joeytwiddle

This dweet was first attempted by BirdsDweet and myself in February 2018.
u/joeytwiddle

We never really finished it, so this is as far as it got. I publish it now, because Slack has now changed their spinner!

Neat!

We can save 7 chars by removing D entirely and using S>7

Crossy Box: Traffic Tourist

Show more comments…
u/joeytwiddle

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).
u/iverjo

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