Hmm, sorry to hear that! I guess I could turn down some of the brightness just to be sure.
Did you start with the training level? (The first egg you walk into, on the stone?) When coming near, it explains what to do. And when you start it, it says “solo mode” and that yes, you control both of them! (If you want, not required of course :p)
Perhaps I could include some barrier to ensure players start with this first level, and get a few seconds to read the tutorial image that pops up.
I’ll try to push an update within the next 24 hours, hopefully it fixes these issues for you :)
