Seasons is an infinity/endless runner game for Windows Phone that was recently released in the Store but had a few glitches that prevented it from loading to Windows Phone 7.x devices.
An update has been released taking the game to version 1.1 and the game loads and plays just fine on Windows Phone 7.x devices. The update also improves multiplayer match making and fixes a few minor bugs that were discovered after the initial release of the game.
The multiplayer games are played over a local network with your character running in the foreground and your opponent running in the background. It took a little time for the two devices to connect in the multiplayer mode which took a little of the excitement out of things. The update speeds up this connect, making the multiplayer mode more enjoyable.
There is a free trial version available for Seasons with the full version running $.99. It is available (and working) for both Windows Phone 8 and 7.x devices. You can find Seasons here in the Windows Phone Store.
