I'm planning to release an alpha version of a video game I'm working on as a personal project. I'm also creating a "Credits" section, that is meant for me to give credit to used sources, and to other peoples whose work I've used, edited, or got inspired from (with their permission, of course); and obviously, my own name.
I'd also like to include links to social network pages, such as my Twitter profile, a YouTube channel, and eventually a GitHub page. As an indie developer, I want people who play my game to have the chance to contact me, tell me their impressions about my game(s), and stay updated on my progress as development goes on. It's another way to receive feedback and reach even more people.
I wonder if mentioning the names "Twitter", "YouTube", "GitHub", and any other, and including their original logo or an edited version, is somehow possible and/or allowed - perhaps including some sort of clause - and what are the limits I'm subject to when dealing with trademarked names and logos under copyright.
