Just finished! With an hour to spare...

Of course I split my coffee on the only keyboard I thought I had in the house on the last day of the jam. After scrabbling around for ages to see if I had any spare, I crawled to the finish line using an Alphasmart Neo as a spare keyboard (oh dear).
Sadly, if it wasn't for that, the game would've had more features. But I'm intending to continue to develop it post-jam. Good luck everyone.
Now I'm going to have a much needed bath!
