This is fantastic! Although it's so simple and basic, it's just bloody genious! xD Oh man, I don't feel like a human anymore after being the first one to get the 8th achievement... it's just... insane.
Anyways, I had TONS of fun playing this game! The different skills, strategies, stories and different outcomes were the things that kept me playing the game this whole time, and I didn't particularly feel bored, just frustrated, sometimes... Kind off weird in my opinion when you Intergration skill is 10 (max.) and you lose on a part where you only need to roll 2 or something... pretty unrealistic and annoying, in my humble opinion.
But still, the concept of the game is just pure gold. I really like it! Just try to maybe remove some of the simplicity and add a bit more details to the game, maybe some icons to the skills, images that fit the different scenes and so on.
Also, making the chance higher of passing when you skill is maxed out would also be a good idea. Yeah, definitely... Can't roughly say how many times I died when infiltrating, especially on the 6th mission...
