Monjarmageddon has been updated to its latest version, 1.3.1, up from the previous 1.2.1 (there's been a short lived 1.3.0 along the way). While the initial ideal for the game was for it to give a similar feeling to old time arcade games, it is understandable that such difficulty and inability to progress was more a constraint than a design decision. Thus, the save system has been updated, allowing the player now to pick one of three save slots in which the progress is automatically saved, changing difficulty on those at any given time. The difficulties have been revamped once again, given new names, a new default, and some adjustments to projectile speeds. The game has been designed to be played in Difficult, but anyone should and could enjoy the game by playing in the now default Normal difficulty. Furthermore, an arcade mode has been added, which allows the player to play without saving in the Difficult level, as the game was originally intended to be played. The changelog list is as follows:

• Updated Unity version.
• Translated Game Over subtitle.
• Improved Game Over screen look.
