itch.io

Games in which the player shoots things to progress, usually with a variety of guns, and other times with bows and arrows.

First-Person Shooter refers to a genre where the camera is at the same place as your eyes: you see (on screen) the scenes just like you'd experience it.

Pretty sure everything is indie on itch.io but just in case you want something extra indie.

Games which have short playtimes and can usually be completed in one sitting.
