I did it!
My very first Ludum Dare comes to an end, and I actually did it: Tiny the Adventurer is done and can be found at http://www.ludumdare.com/compo/ludum-dare-23/?action=preview&uid=12918 .
The game is missing loads of things and I’m afraid it’s actuallt quite crap, but I’m glad I finished it (in one day and a half) nonetheless. Next time I’ll probably do better. =)
