While Sega hasn’t really given a specific release date for “Sonic Mania,” an email from Amazon has revealed that the side-scrolling platform game has been delayed. The new estimated release date of the game has been outed as well.

On Monday, several gamers who have preordered “Sonic Mania” from Amazon received emails from the electronic commerce and cloud computing company, informing them of the sudden change to the release of the video game. According to Amazon, Sega has changed the estimated delivery date of the item to Sept. 4, 2017, so it will be making an effort to deliver the game to players as soon as it is available.

“We have received new release date information to you preordered video game. The release date for the video game listed below has been changed by the publisher, and we want to provide you with a new delivery estimate based on the new release date,” Amazon’s email read, as quoted by Hey Poor Player.

This is actually the second time that Sega is pushing back the release date of “Sega Mania.” GamingBolt reports that the game was originally due for launch this spring; however, the publisher announced that the game won’t be arriving until this summer.

While many people associate summer with just the months of July and August, September is also counted as part of the season. This is because the said month bleeds over into fall, which is the start of the big Holiday season, as pointed out by Comicbook’s WWG. Also, it’s worth noting that this time around there isn’t a vague summer release date for the game given that Sega did not mention a particular summer release date the first time it delayed the platformer.

“Sonic Mania” is a 2D game with retro style reminiscent of the 16-bit Genesis games. It is slated for release on the Xbox One, PlayStation 4, PC and Nintendo’s newest console, the Nintendo Switch.
