Don't play it here, if you play it on the sinister design website you can recruit an energy golem (named dorgon) into your team. (An experimental one who can move)
Its alright, but I expected a more climactic ending, at least a cutscene or a more interesting boss. Seriously all the last like 7 levels are the same. Makes me feel like i played a huge game, took a long time and got nothing from it
