This game is AWESOME, Love the design, love the gameplay, love the challenge and the cruelty that comes with it of a Roguelike. It's entertaining as hell and it's one of my favorite games lately. Though sadely he suffers some flaws, the fact that the upgrades are so fast to get (I got nearly all of them by level 2) the fact that the bosses are basically all the same, and that the Ammo is easy to find you can easily kill a boss by spamming rockets or grenades at him. All of those are flaws yes but they are not really bothering me as much as the lack of progression. You arent rewarded at all for finishing level, the cutscene is the exact same cutscene and then you do it again, the levels arent particularily more challenging when you advance and your character doesnt evolve. And that's what kills it for me. It would have been so good if you just added some more cutscene or did something to help the player fell like he is making any progress.
Anyway great game.
