After watching ElysiaGriffin play Tunnel Bug, it was apparent that the timer bug was still present. I believe it's actually due to timezones, because it wasn't occuring for me in the UK (GMT+0) while ElysiaGriffin is based in the East Coast US (GMT-5).

I also found you can still go out of bounds, so I blocked that out too.

I'm gonna try and get the Linux build ready tomorrow. It'll be the last update I'll do for the duration of the rating period for Ludum Dare.
