Hindsight makes me agree with you! I thought TGB was around the same level as Game Maker in terms of rapid development. But soon enough, I discovered that apparently you need to script up your own behavior to enable keyboard control of your player. That's not so rapid. I admire TGB's potential for code reuse in production environments of independent game software vendors, but unfortunately it's not "rapid" enough for this particular scenario.
I actually was hoping to start a bit earlier, but I had a few... problems... this week.

So that concludes my attempt for Session 13. Funny thing is that the theme was "Time", and I ran out of time.
I'll definitely be around for Session 14.
