MouseCraft

Added full keyboard support - now you can play the game solely with a keyboard.
Added Xbox 360 and Xbox One gamepad support for Windows and Mac OSX (support for Linux is pretty experimental).
New languages (Italian, Dutch, Russian, Simplified Chinese).
Added a "language sniffing" mechanism - the game will now set the language according to the operating system language.
Increased the performance and quality of videos for Mac OSX.
Optimized a lot of graphics stuff - reduced the number of draw calls by 30%.
Added functionality to Effects toggle - setting effects to "Off" will result in launching the game in a mode suitable for older, low-end computers.
Added a green outline showing the currently active Moving Brick.
Added an option to increase the speed of the game without releasing the Mice.
Moved all Brick outlines to a higher layer so they are more visible during Active Pause.
Feature cutscenes will no longer appear if you have already completed the level where the feature was introduced.
Lots of Level Editor bugfixes.

Windows: Xbox 360 and Xbox One controllers should work out of the box if you have the necessary drivers. A PS3/PS4 controller can be used with Motionin Joy application and emulating Xbox 360 controller.
Mac OSX: requires free 3rd party driver by Tattiebogle.
Linux: It really depends on the drivers.
