The Messenger is a real gem of a game. Ninja Gaiden meets Metroid, lovely pixel art (should run on anything), a banging chiptune soundtrack, super tight gameplay, funny writing, and it's currently 80% off. If you like platformers and metroidvanias you got to check it out.

Listening to this while going top speed through the level, doin sick ninja moves fuckin wrecking shop, it's some of the most fun I've ever had playing video games, the whole game is such a treat when you unlock all the movement upgrades and get good at flying around everywhere
