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.

It’s been a while since I played it, but I think They Bleed Pixels might fit the bill on both counts.

Also I recently started The End is Nigh which is another Edmund McMillen game very similar to Super Meatboy. Seems good so far.
