the final installment in this series is world of goo at 8 months old (april 2, 2007).
it’s now almost 4 months after we thought we were 3 months away from finishing the game. we continue to fool ourselves and think we’ve got another 3 months left to go. the delusion doesn’t stop there. as you can see in the “world menu” (which would eventually become the main menu) we thought we would have 7 chapters in the game. riiiight.
probably the biggest change in this revision is the new physics engine. we scrapped our home grown physics engine in favor of ODE, which gave us a lot more flexibility with the kind of puzzles we could construct. it stung to toss that code away, but it was the right thing to do. it allowed us to create a much wider variety of puzzles.
when you play this version, check out the first level (Going Up). it has been set up as a kind of physics playground to test out different ways to have balls physically interacting with the environment. you can get it here, and once again, if you played a previous build don’t forget to delete \HKEY_LOCALMACHINE\SOFTWARE\2dboy from your registry before running this version.
there’s also more experimentation around showing progress to the player and the end of level sequence.
and that’s about it! we’ll stop here because the rest of the game’s evolution was much slower. it happened in baby steps with new levels, new ball types, lots more playtesting and gameplay tweaks, and within 4 months would become the chapter 1 demo we submitted to the IGF and made available to people who pre-ordered the game.
we hope this made for interesting reading!
