Took me many, MANY tries but i finally beat the game today. According to the in-game statistics, i had 37 Deaths, 0 End Boss Kills (wtf? i killed it once already -_- ) and 78 Items along with 15/97 Secrets Found.
I had a lot of fun with this game and i can foresee a lot more fun with it in the coming weeks because there's a load of stuff to do, including the DLC. My only problem with this little gem is that it lags a lot, i googled for some fixes but it seems that there's little that can help short of a super processor and even then, that's no sure-fix.
I highly recommend this game to everyone, you don't like isometric top-down shooters you say? Screw that, still try it, $4.99 is a steal and there are some lite-RPG elements thrown in for the hell of it and the soundtrack is super awesome. There's no excuse not to try it, unless you're easily disgusted, then that i can understand.
