I like this game. A lot.
I feel though, that it should have multiple protagonists. Cody, Shawn and Mike. Those three. Each boy having a season for himself to be the MC. For example, 6 updates could count as 6 episodes and one story/season where Mike is the MC is finished and then another boy takes over.
I just don't see Mike as a protagonist who fucks all the girls in the game.

Multiple MCs with a decent storyteller could be more fun than another harem game. 1 season = 1 MC trying to bang/make love with his milf. Maybe have angel stuff reserved for solo mom love paths and devil route for harem choices? Tease other boys and their story, then one of them becomes the MC in s2 and so on. After they achive their goal have them all vacation together on Jocasta island or something as the epilogue.
Good luck with the game in any case. I'll be following
