Dweet Invaders 👾 #interactive #game

u/tomxor

neat
u/rodrigo.siqueira

"Space Invaders was initially seven kilobytes (KB) and had to be cut down. He spent three months editing his code to be able to fit on the four KB rom cartridge." (Wikipedia)
u/Coalshork

absolutely nuts
u/lewdev

Amazing Dweet, u/KilledByAPixel! And thank you u/rodrigo.siquera for that tidbit. I didn't think there was so much code golfing done back then too, which was probably a lot more normal then it is compared to now.

141/140 I broke the matrix

u/prplz

When the order of your for loop isn't important you can make it count backwards like this for(i=10;i--;)
u/Galaxtone

oh nice thx for the tip I'm new to this code-golfing site
u/Galaxtone

also I saw something about using with(x) so I think I'll use that for future stuff :p
