Haven't noticed this mentioned elsewhere (read - did a brief search and called it good), so a heads up - online South African game dev magazine, Dev.Mag, has just released an issue featuring Aquaria. If you've lurked around the TIGSource forums, you'll know Tr00jg, and he's interviewed Derek and Alec for it. So,
enjoy.
Chances are it's things you've already heard, but hey.
