Alright, to begin with let's get the tricky stuff out of the way.
First of all, this game is cheeky and doesn't shy away from cracking jokes at everything, itself included. If you're easily offended, you might want to keep that in mind when making your decision, but ultimately it's all light-hearted and carefree. So don't make it a political thing, it's not.
Secondly, while it's true you can play this for free on Kongregate, the Steam version (like Kong premium version) adds extra features (including new game plus), an entire new zone with bosses on illegal stimulants, supports more resolutions and you get the entire soundtrack, which is, might I say, really, really good.
Now with the disclaimers done and over with, let's get to the actual game.
It looks old school and cartoony, with turn based combat in which you slash, hack, blast and nuke your way through loads upon loads of critters, ranging from cute bushes (never thought I'd use that phrase seriously) to intimidating elementals. Elemental strength/weaknes system is in play, and there's plenty of elements and status effects to play around with. There's a lot of room for experimentation with gear and skills, and even bosses can be beaten through different approaches.
The soundtrack, as I said already, is AWESOME. No really. Just listen to it and appreciate it. It does a lot to round up the game experience. HFX has done an awesome job yet again (the only kind of job she ever does it seems).
It's not a hardcore RPG, even if it offers its challenges, but that makes it no less fun. Just a word of warning: If you decide to play this, better wear a helmet, because those shards of the fourth wall are going to be a-flyin' all over the place.
