So I'll be straight to the point. I wanted to get your version of spelunky working on my chromebook, ChromeOS. But the problem for the way i did it is one thing. I used ARC Welder to make your apk version of the game into a chrome extension/app. (before i continue, yes i know, i can sideload apks instead and use google play store and so on. but the point for me was to not sideload.)  ANYWAYS, the problem is the game loads and all but the game is a black screen. not the menu when i press ESC or the touch controls. just the actual gameplay is black. there is sound and all. just no well, spelunky. lol. if you have any idea why please do help me. and the game does work on my phone fine so idk.

I'm not familiar with Chrome OS, so I can't help you much. I suggest you try to run an HTML5 version. Either using this link or you can download this archive, unpack it and run the game using the webserver, for example, this one).

Did you manage to get the game to work on your Chromebook? Have you tried any of my suggestions? Your experience can be valuable to other people.
