You know, this actually *almost* works great on mobile browsers! If you're doing an update, maybe you should make it so it reloads if you left click on the ammo icons in the top right corner?

It's funny, I originally thought there's no way it could be fun on mobile with those controls, but indeed, it sort of works. For now it's possible to reload with a two finger tap (strange Unity touch->mouse mapping), but of course that's hardly usable.
I'm going to release a post-jam update, including an Android version, when the voting ends (Sunday). I was thinking about a mobile-only reload button below the cowboy, but I'm still considering my options.
