I hope you're fine with me responding to this publicly! I'm always super pleased when I hear from folks who played my stuff when they were young. It's often hard to respond with anything that feels worthwhile, in part because it's a bit of a mindboggling responsibility to know that your work influenced folks in early and lasting ways. "Not really bigoted but anti-violence" is doing a lot of work here, and while I can't speak to your personal circumstances, I feel like video games in general have been ill-served by the fact that the loudest critics of their violent themes have been a bunch of disingenuous prudes and conservatives.
We've recently seen a bit of a backswing in terms of enthusiasm for "wholesome" games that has faced justifiable (if overzealous) skepticism. As the Wholesome Games organizers point out, calls for more games that are non-violent can be a mask for reactionary and normative values on one front and can prompt impossible purity tests from well-meaning leftists on the other. Personally, I'm a pacifist and I'm glad that I've had the opportunity to explore the complexities of committing violence or destruction in the course of the greater good in a way that has resonated with folks. Doing right is hard.
(And in case you or others reading this aren't aware: there's more Exploit! Me and my partner @maw at @fpg continue to work on Exploit: Zero Day, a free web-based hacktivism puzzle game that carries on exploring questions of what to do with what little power you have when facing systemic oppression.)
