Rayman Legends was originally announced as a Wii U launch title, before being delayed to February/March.
However, the decision to release the game on multiple platforms has seen the Wii U version slip to September in line with the PS3 and Xbox 360 ports.
Going under the name Zeta69, the former Ubisoft employee expressed anger at the delay, having spent six months barely seeing his wife, kids and friends to ensure the game was ready for February.
"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," explained Zeta69 (via NeoGAF).
"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 (gamescom, 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.
"For practical matters, you'll have to wait for some months for the game to be released and will most likely serve for more content to be added and do it better. For us, this means we've spent six months barely seeing our wives, kids, and friends for nothing because, after all, such haste wasn't needed.
"Believe it, it was a hell to swallow these news."
Blaming "men in ties" for the decision to delay the game, the former developer went on to say that Rayman Legends is an excellent game, and that fans shouldn't turn their back on the franchise.
Ubisoft officially unveiled the much-rumored title during its 2012 E3 press conference.
The game features new playable characters such as Murphy, who is controlled using the GamePad on the Wii U.
Players swipe the tablet's screen to control Murphy, using him to clear a path for Rayman to traverse and take out enemies.
A multi-platform release was rumored after Ubisoft failed to rule out Xbox 360 and PS3 support.
