Yes, i very much hope so! It is mostly down to workload, as it's only me doing the programming and platform support, so we are a bit limited what we can do in parallel. But i love itch, and want to bring the full Dome to it too. Did the same for our first game, making it even a bit cheaper (but only a month or so after the Steam release, because of the workload prohibitting doing it in parallel).
Try and hire some new and better programmers to help with the progress and development of the game. Also, I would suggest that you release the full version of dome Romantik on steam first, because more people have access to steam and because it will become popular and possibly make it to the front page of the steam store, which therefore means that people will see it and want to play it, therefore more popularity = more ad revenue for steam (main Dome Romantik launcher) to better make Dome Romantik a favourite free game to play.
P.S.
try and focus on getting some money to hire or seek help from some other game devs, so then you don't burn out everyday trying to get this done because people are peer-pressuring you. Just take a break and chill out with your family and friends. Here's a little tip though, maybe go onto reddit and try finding some game developer groups and asking if they want to help you with this already extremely successful game.
