Er, g'day. My name's Garry. I'm an Aussie, but don't hold that against me. I participated in the first two Adventuron game jams and had a lot of fun, so I'm planning to enter this one, as well. I've already got a few ideas floating around in my head. If I can get these ideas to work in practice, I can promise something very different to what you might be used to. It will be very puzzle-centric.
I'm hoping to see a lot of the previous participants, as well as lots of new participants. If you're a beginner, don't be scared. The folks on the forum are very friendly and will help you out with any problems you may have. If Adventuron is busy, I'll be here as a backup.
I'll just give one word of advice. Start now! Don't leave it until the last minute or you'll run out of time.
Hmmm, maybe two words of advice. Test. Test. Test. Aim to finish at least one week before the deadline and ask others to test it for you. A good tester will find all sorts of issues that you missed yourself.
