Totally, I don't even have a cellphone let alone a smartphone. 2048 was the only version I played. It got me so interested I even made an awk version. That's what I liked the best, all the creative versions people wrote based on it. Someone on here wrote, 'the only thing more addicting than 2048 is making a 2048 clone.'
I have no idea why you got multiply downvoted. I tried to compensate but doesn't seem to have helped much.
Would certainly love to see your awk implementation. I think I heard of a sed one, so awk would be the next logical progression, may be REBOL too, or its new incarnation Red.
It's long past where I should have just rewritten it in perl, tcl, or python. Running x1k might be a good starting point. You can read in onek what are the keys to press, I redefined them from the vi home keys that the awk script uses by default. Have fun!
