In addition, to sell games made with Construct 2 you'll need at least a Personal License, and unless you have it on Steam and it doesn't show here, your profile doesn't seem to show that, so I'll explain. A Personal License lets you earn up to $5,000 from games you make (in total, not per game), and the Business License removes that restriction entirely, allowing you to earn unlimited revenue. So, if you plan on selling any games you make using Construct 2, you'll need either license.
That aside, I wish you luck with further development, .
