Hard platformers with banging chiptune soundtracks? - Feddit UK

I’m really in the mood for a game like Shovel Knight after listening to some chiptune tracks the other day. Something fair, but challenging would be ideal. Must have a good soundtrack! Along these lines I’ve already played: - Shovel Knight - Celeste - The Messenger - Hollow Knight (well, in terms of the difficulty not the music) Does anyone know of any I’ve missed? They don’t necessarily have to be modern indie games - old NES/SNES games for example. SMB3 and SMW are classics.

Micro Mages? Essentially a modern nes-game, co-op for up to 4 players.
The fact that this fits on a NES cart is really neat! Thanks for the suggestion - I hadn’t heard of this one before
the game from steam also comes as a nes rom-image, you can use it any nes emulator. I used Mesen, got quite a bit more customization & scaling options etc… and save states because I suck at it :D
