seriously though i would like to experiment with steam but not got round to it.
ITCH.IO has worked out perfectly for me as a relatively new developer who enjoys a bit of creative freedom.
I would suggest that if you can do a campaign here or on a crowdfunding site to raise $100, then that would be a natural way to get the funds for steam.
Finishing the development of the game is surely more important that the means of publishing it?
Stick around here, Post devlogs, State your goals and hopefully you will find some real support here (support you may not so easily find on steam).
That would be my advice. have followed you and will be looking out for further developments ;)
