Hey fiGames,
Definitely publishing on Switch would be a great achievement. I have tried mobile and to be honest it could be better (so much better). Regarding your intentions to use a publisher... well... I've heard so many bad stories about publishers and game developers that If I were you, I'd tread carefully along those realms.
I'll keep an eye on your game. It will be interesting to see it finished (you are almost there pal). I still got some bug to fix on my own.
Cheers
