I'm currently developing a small, twitchy SHMUP built for single player as well as co-op and I've heard many times from other sources that I should more than definitely pick one or the other, not both. But here's the problem: https://www.nextpeer.com/ Their -FREE- indie solution is free for unlimited MAU, all they need is to put ads in your game if you go with that solution. But my game is designed specifically around a $0.99 price point. Would it be considered dirty/nasty to throw in the ads in an as non-disruptive manner as possible, or is it just asking for problems from potential fans? Advice?
