I checked out an interesting sidescrolling game by the name of Whispering Willows. It was indie and it was partial horror, all mixed with puzzle elements. I approve!
Had this small happening while playing Overwatch in Quick Play one evening. A supercharged Roadhog kept killing the team, who was powered by three Mercys. While it took awhile for the team to figure out what to do, I already saw parallels from an old side-shooter game I used to play; Gradius. Suffice to say my approach worked.
