Mobile Version
"First of all only the cellular stage could be relatively simply ported over to mobile. All the other stages will need major control scheme changes, mechanics changes and probably a ton of extra optimization etc. -- Additionally if by "mobile" you mean iphone, then that is even more complicated as we current programmers don't have macs, which are needed for iphone development (I also don't have an iphone either, but I don't know if some other programmer has one). So very unlikely, but I won't say never." - hhyyrylainen on reddit
A newer post about this is here: https://www.reddit.com/r/thrive/comments/jb5tub/mobile_version/
Now that we use the Godot engine, at least an Android port should be easy-ish technically to make now, however the control scheme problem is still there. Also we likely need to have lower end graphics for phones. And finally, publishing on phones have actual fees associated with them so unless the mobile versions were to cost money, they would be a net loss in terms of income for Thrive.
