Yesterday Ubisoft announced that Legends - formerly a Wii U exclusive - will now also be released on Xbox 360 and PlayStation 3.
It also quietly confirmed a delay to September - the second slip in the game's development history following the move from November to February 2013.
Posting on a Spanish forum (translated by NeoGAF), the alleged developer - using the name 'Zeta69' - called the news "hell to swallow" and suggested Rayman Legends was ready to ship this month as originally planned.
It's not clear exactly who the forum account belongs to, though its post history suggest it's that of a legitimate Ubisoft employee.
Responding to disgruntled fans, Zeta69 posted: "I completely understand you but you have to understand one thing. This is not a decision taken by the development team, this comes from really really high up, so please don't pick on the game."
The post continues: "If you're pissed, imagine how we feel. Think on the situation, we've been making overtime with this game practically since May preparing E3, and then almost a demo per month (gamescon, Wii U presentation, shops, eShop, etc...) and at the same time trying to actually finish the game.
"We had a first delay because it was obvious we couldn't finish on time but we gave it all to be there on February. What face do you think we had when the week we had to close the game we're being told it's not going to be released? I couldn't believe it."
As a consequence of the delay, the poster claims that more content will likely be added to the final Rayman Legends release, to the detriment of developers' personal lives.
"For us, this means we've spent 6 months barely seeing our wifes, kids, and friends for nothing because, after all, such a haste wasn't needed. Believe it, it was a hell to swallow these news," the post reads.
"Even then I'm firm in what I said back in the day, Rayman Legends is an excellent game and will still be, and the team that's making it doesn't deserve to have your back turned on them just because some men in ties one day took a wrong choice. This industry is really that shitty."
Ubisoft has declined to comment.
