Like the small JS version this also has the bug where you can summon more tiles by pushing again in a direction where movement isn't allowed.

    puts(W&1?"WIN":"LOSE");

Shouldn't exit(W&1); be "good enough" while saving some bytes?

While 487 bytes is impressive, it feels like you should round up to the nearest power of two...

Doesn't run correctly under windows. The code relies on the system call "stty cbreak", which is linux specific.

'stty' is not recognized as an internal or external command, operable program or batch file.

I would love to read comments instead of downvotes. Where am I wrong?

`stty` is not Linux specific, it's common to all Unix-derived systems (including Mac OS X, for example). Windows is not Unix-derived.

well, bugs or not, 487 bytes is a new high bar... I guess the lisp lads might need to curl up their sleeves.
