Great work. For those on OSX, replace "seq" with "jot -" and it works.
(perhaps you could check for seq at the start and use "jot -" instead.)
The "wasd" keys get me each time. I've not lasted more than 10 seconds! Any chance of using arrow keys or hjkl instead?
Thanks! I didn't know about jot on OSX, I'm gonna fix that. I'm thinking of making the keys configurable via command-line parameters (as well as some other things in the game). I picked the "wasd" keys from FPS games :)
