Tess is a platformer run-and-gun game. It follows the story of Tess, an odd little girl who had a bad day.
You run and you shoot and you can pick up exp to increase your total number of hearts.
This game was made in Java so it should work on Windows, Mac, and Linux. Tess OST (bandcamp): https://girakacheezer.bandcamp.com/album/tess-ost
