I'm glad you liked it. The paintball idea is a neat one.
It's gratifying to hear that the tutorial , as it were, was helpful. I've never done something like that, but I wanted it to be possible to play without referring to the game page. What's really neat about the UI is if you had a controller, using it would flip all the buttons to display buttons for the controller you're using.
I spent a fair amount of time on sound design. I'm glad you liked it.
