Movement is very fluid in the game and works very well, which is needed for a platformer. It is fun jumping around and there are no consequences when falling too far, so it allows for plenty of experimenting on where one can travel in a level.
This is a game made to be extremely difficult, in the vein of Super Meat Boy or N+ the player will die and die a lot. This can be frustrating a time goes on and the further one gets as the game really increases difficulty.
Players get an invisibility cloak in the game as a main mechanic where it is used to sneak around. Of course movement is limited when in use which makes for some great puzzle aspects to the game when trying to figure out how to best sneak around.
The game focuses on exploring and trial and error, so death will happen quite a bit, but luckily the save system is quite generous which allows for one to test out areas with ease and no fear of dying over and over again.
