I'm making a FTP game with gacha mechanics

So, I graduated from college with a video game design degree over a decade ago and I have yet to really commit to making a game. Now with AI, I can finally do everything. Having it programmed, having art, everything. I can actually focus on what I like doing, the design part. From my design doc: Reelbound Resonance is an (currently) FTP gacha game where you are chosen by a mysterious artifact to become a Resonant. As a resonant, you summon extra-dimensional waifus called Reelbound to battle rogue Codex users through dynamic 3x5 slot reels, where each character’s personality and element directly shape gameplay. Guide your waifus, master the reels, and uncover a world that’s playful on the surface but corrupted beneath, where every spin can be life or death.
