Whatever this indie game is, it is a retro-styled mix of Asteroids & Lunar Lander where you're supposed to land on specific spots of various meteor/rocks without crashing your ship. I don't know which game engine this game uses although I know the fact that it is on the same arcade system as Skycurser.
The makers of Skycurser, Griffin Aerotech, had made the Airframe as far as I know but the information about how indie arcade games are being made using Game Maker Studio, Construct 2 and Unity is quite scarce. The interesting thing is that you should be able to publish those games made using one of those game engines to HTML5 so that they can be played on the Airframe arcade machine. It is an indie game answer to many of the professional PC-based arcade systems although some of the games like Skycurser are old-school looking instead of going towards the current-gen but that's indie game for you. For indie games on consoles and Steam, they can be ported to other systems with minor changes. Optionally, the other versions will have additional features.
So here's the thing, you approach the Skycurser development team to see if you want to make your own indie arcade game for the Airframe like the developers of Rashlander did. There's one major problem though, the development kit and the edition of whatever game engine that allows HTML5 export can be EXPENSIVE AS HELL and I have no idea on how you will obtain the Airframe stuff.
To put in a bunch of arcade elements like Operators Menu, Hardware Check and Coin/Credit Control into those game engines will be no easy feat although the Unity engine already opened doors for arcade game development in Japan.
I don't know what the controller will be like for the arcade version of Rashlander and the PC port may add additional challenges in terms of controls. The arcade version was already out late last year and the PC port will be released sometime this year.
