The first twenty-four hours following FEZ's birth seem to have been littered with bug reports and crash complaints, and developers Polytron have acknowledged the issues and are beavering away at working on a patch for the Xbox 360 exclusive alongside Microsoft.
"FEZ had more testing done in the past 24 hours by about TWENTY THOUSAND PEOPLE (!!) than it had in five years," wrote the dev team on their site. "So, as it happens, bugs popped up. Some pretty serious."
Serious indeed. Some of the bugs already reported have include the event that "a small subset of older Xboxes with smaller hard drives can’t run the game at all"; additionally, "the game has trouble running off a USB stick. Crashes are occurring in specific levels or situations. In a rare situation (exiting the game from the “wall village” interiors), the save file becomes unusable. Nasty stuff."
Whilst we at Dealspwn are yet to encounter a game-breaking crash just yet, we do know one or two people who have, and Polytron are asking that if anyone does experience technical difficulties, popping an email along to firstname.lastname@example.org would be of great help.
