Another free game on Epic. Store description:
Arguably the most well-known indie game of all time, Cave Story+ features an original story brimming with personality, mystery and fast-paced fun. Run, jump, shoot, fly and explore your way through a massive adventure reminiscent of classic 8 and 16-bit games!
Wow, I remember playing this waaaaaay back in the day on PC. And then I heard it was coming to the 3ds and got it there.
