Derek has written an interesting post
over at the Bit-Blot
blog, talking about Aquaria's evolution as a game and some of the design decisions that drove its direction. It's part four of a seven day ramp up to the game's release on Friday.
Parts one, two, and three have been great, well worth checking out if you haven't already seen them: Part one
featured some of Derek's concept art (shown above), part two
featured an excellent arrangement of some of the game's music by Alec, and part three
featured a lengthy and entertaining interview with Jenna Sharpe, the voice actress for Naija.
Aquaria is due to be released in three days time.
