Honestly, I think you've put a lot of effort into criticising a game you clearly don't "get". 

It's a bit like criticising a bullet-hell game for being unrelenting, or a roguelike for permanent death. If it's not the sort of game you enjoy, then perhaps spend some time on other games?

Your criticism also appears rather contradictory - you want it to be easy to explore the maze AND to have a map of the maze given to you?

The fact that this is not like "todays games" is exactly the point.

It's linux on ARM, so you would have to compile for the platform - and I think it runs Open GLES, which you can use directly, or may be able to use the GL4ES wrapper. The biggest thing would be to make sure it worked with the controls.

By the way, if you're planning a Linux version, *please* can you check out the RG351 console(s) (based on Ubuntu 19) - they would be the perfect home for this game and already have some excellent native titles.
