It's been a while since I played (like 18 months or so). Theoretically, the Karma system was actually implemented as of 0.10.0, and was to see actual use in 0.11.0. To date, this has been functionally a kinetic novel; you might see minor deviations based on your choices, but nothing that would impact the overall trajectory of the story. There has been some degree of corruption, but someone else will have to point out if there are any choices you make that significantly alter the overall story, rather than determining whether you get version A1 or A2 of a particular scene.Can you Bimbofy a character?. Also How does the Corruption system work exactly in-game?. Do the females personalities change or start to wear more lewd outfits?. That type of thing. The Character models look cool and so do the animations. A Lot of hard work has been put into this project. Love corruption in these types of games,but they're mechanics are not all the same. Some are heavy-Corruption and some are subtle and balanced about the corruption. Turning a nerd into a complete unashamed harlot. Or Romancing every girl having them fall in love with the MC.
And no, no major bimbofication (certainly in the sense of physical changes - some of the corruption may make some characters more willing to be slutty).
