"The biggest mistake in Boom was trying to cram too much into the game... Not only were we trying to make just a really good Sonic game, we were trying to add more to it. We overextended our grasp in some ways. We're trying to add in a bungee mechanic, and we're adding combat, and we're adding puzzles, vehicles, hopefully a more compelling story and a bunch of different environments. And it's just a lot, you know? If there's any lesson for me, it's that being too ambitious can be bad."
