Unfortunatley i cannot help you because i also have no linux. But I am anyway interested on your project. I am working on a dungeon crawler project and it is already running fin with native GLBasic 3D. But maby with Irrlicht i could improve light-settings.
I did a very basic scanline shader already with ALPHAMODE. But at the moment this has no priority. But at the end it should look similar to "Super Hydorah" https://www.youtube.com/watch?v=pi-xu06RdO8 For now I'm working on soundFX and first level BGM.
I'm just a hobby programmer too, but my thoughts were to taking unpaid holydays from my fixed job to gain more time to program. But I think I will not make the kickstarter. It seems to be a (to) big risk for me.
Funny,. Somehow also I thinking about changing now away from Android. But in my case it's because I now see behind marketing. So I'ts nearly impossible as an unknown "real independent" developer to get anything. It's so many fakery behind the scene
@bigsofty Yes, Space Harrier is the main influence @MrPlow The video is 30fps but on real hardware (normal Intel onboard graphic) it runs on 60fps It's all written in GlBasic. In my opinion GlBasic is heavy underrated. Performance is good and it doesn't have this huge overload like Unity @erico It seems since 3D-polygon graphics came, no one made anymore games like this (except bad 3D remakes)
After few projects I did with Unity it's time to do something for RETRO-memories. And what's better to program this as GlBasic? Well, I found nothing. I started a new game project. It's still very early state but if you like you can watch the actual state on my site mountainsoft.ch.
