The problem with the banner stuff is that they're not designed for onboarding, they're designed to continue an already established brand and keep them at the front of people's minds.
When I walk past a coca cola ad and my eyes see it for a fraction of a second, and my head is like 'hmm im thirsty, I could really do with a nice, icy coke right now'.
Or, if its say a store brand you don't know of, you'll make a subconscious note of it, and when you see it next to your usual brand when shopping, you take more conscious note of its presence as a 'legit' brand, and try it out instead of your normal choice.
Neither of these situations are the case with Hive. Nobody is going to randomly remind themselves Hive exists and they just forgot about it until now, and nobody is going to see it in their daily lives after the game. It's literally the wrong form of advertisement... (no offence to the person who did that).
I think some professional market research and business training may be necessary, rather than a bunch of random bloggers throwing out ideas, getting shut down, rinse and repeat
