I rather advise against playing this game. It certainly has some clever ideas, the variety of gun-recoil-based platform challenges could have been fantastic; but nothing in this game seems well realized. Except perhaps the bugs.
I noticed quite a few programming issues. When switching to fullscreen, the game window would get stuck in a corner of my screen. When adjusting the resolution, it occasionally activated fullscreen and otherwise did nothing. Cutscenes would have odd bars of random environments on their sides, occasionally sound effects would last several seconds after there ceased to be anything causing them, and occasionally the physics engine just completely failed to behave itself and the gun boost around which the game revolves would just completely not work (and yes it was charged.)
As well as the bugs, it seems rather poorly optimised. The lag was nigh-unbearable and severely hampered gameplay; many times moreso than on games with much more intricate graphics effects and onscreen stuff to keep track of. I would have tried to adjust settings to reduce the strain, but no such option exists. Neither does the option to stop the screen from shaking obnoxiously in two of the areas.
While it has amusing and creative boss fights in theory... they go on a bit too long... and \were probably supposed to be able to hurt you and not occasionally fail to even touch you with their attacks... and the final boss probably shouldn't have been designed so that he might never use any attack except the one you can counter to defeat him.
While the premise itself is what originally drew me to it, even that gets a little bit ruined by the end. The next to the last sequence of levels seems to be a mean spirited assault on pretentious games that, aside from containing no discernable humour and being pointlessly aggressive, constantly hammered in its implication that video games are inherently not art... not a supposition I would support.... and the entire game ends with the main character just sliding towards the camera and shouting 'Videogaaaames!' I'd call that a spoiler, but the fact that it doesn't have anything to do with anything is kind of the problem.
But aside from the many, many failures of construction and questionable design choices?
It's a decently creative platformer with different controls and a fair assortment of levels that gradually increase in difficulty. It's got a good assortment of extras. And the sillyness of it does amuse for a while... but I can't really enjoy any of those things in the mess that this game turned out to be.
