You find a community-made "homebrew" version of Shovel Knight designed for the PSP.

Yes, with one massive caveat:

Since the game doesn't have its own on-screen buttons, you can use third-party apps to overlay virtual controls that mimic a physical controller.

However, with the right setup, techniques, and a bit of patience, playing Shovel Knight on Android is not only possible—it can be genuinely enjoyable.

The game runs at a locked 60 FPS on almost any modern Android device.
