I bought the game on day 1, then wrote a review and got a refund. https://steamcommunity.com/profiles/76561198097980543/recommended/3102290/
The game does work with sinden, gun4ir, and any other mouse-based light gun. The problem is that there's no option to disable the on-screen gun and crosshair, and hide the OS mouse cursor (lol). Like the last Buck Hunter game for PC, someone's gotta make a mod to do this
