Fans of Spelunky will be pleased to know that running Spelunky Classic HD on Linux is now a Snap, literally.
To install it, you need Snap package support of course (install instructions here). Once you have that setup, installing it couldn't be easier! You can run these simple commands in terminal:
snap install spelunky snap connect spelunky:joystick
If you're on Ubuntu, you can also visit the store entry for it on the snapcraft website for a direct install link which will open up your Software Centre directly to the game.
To be clear, this is not the same version of Spelunky that's on Steam, this is the classic version. It's using the source code from this GitHub repository, which adds a couple of extra features like different aspect ratios, touch input support and more. The Snap was made by Martin Wimpress, one of the same people behind the recent Snap package of TrackMania Nations Forever.
Really sweet to see more games get the Snap package treatment, for the times when you just want something really simple and easy to get you going. Runs quite nicely in my testing with keyboard controls, although I couldn't get my Steam Controller to be picked up properly even while using SC Controller.
