Pretty good first episode with very likeable LIs and great renders. The similarities with Eternum are impossible not to notice but it has a lot of potential to be a great game on its own.
I'd say the biggest weakness of this first episode was the lewd scene with the masked girl at the throne that was just very generic and abrupt with not that much of a build up, especially if she's gonna be one of the main LIs in the future. I hope the scenes with the other girls will be more elaborate, especially the animations since it has such great renders to begin with.
I also caught a few typos but nothing too major. There's also a bit where MC and Hayley are setting up their running date that doesn't make much sense where she asks if Sunday is good and he confirms and then he asks her if Sunday is good, so you might want to look into that.
