Original Game
There are two modes, move mode and freeze mode. move mode allows you to pickup and place objects, such as stacking a pile of boxes to get to a high place. Freeze mode lets you freeze objects in place, such as freezing a crate over a gap, so you can get across without falling in.
You should just be able to install the vpk through vitashell.
I've known about the PS Vita for a while now. I started learning Godot a few months ago when a port of it came out for the vita. I used this contest a learning experience to get familiar with the engine and learn how to optimize any of my projects to run on low end hardware.
