The inspiration from Lessons in Love is VERY obvious, it's omnipresent, from musics, to themes (unfeeling dickhead focusing on his desires/Memory loss or finding himself somewhere without knowing how he got there/Seeing weird or fucked up things while hallucinating), character traits ("perfect" smart blond who's actually miserable/small girl with dead brother/cute girl working as a maid, MC obsessed with maids, spending all his money and flirting, maid girl acting like she doesn't like him and gets hurt ETC), major plot points (All of this being a game for the gods, MC losing his mind, THE FUCKING RESET), place names (Koi Cafe), outfits (Koi Cafe outfit, and more), syntax (the whole gods but with a straight lign going through it thing, even more so the same thing but three times in a row), scenes and character placements ( Seeing some backgrounds appearing in multiple games is nothing new, and isn't usually an issue, but when there are as many similarities as there are here it raises questions) you even put HEXADECIMAL which yeah isn't exclusive to LiL, but it's so frequent there, that it looks suspicious in a game that has soooo many references to an other game, to see it use one of said game's most used and niche feature.
Anyways, I liked the game, it's like a lesser version of Lessons in Love, which we can see was a huge inspiration for it.
But as the game goes on, the inspiration and the allusions to LiL start becoming too much, it becomes TOO similar, ffs you even show a still image of an EGG which I'm pretty sure is also a thing LiL did.
I like the allusions to it, the little winks here and there, but when it becomes TOO similar and too many things are taken, it strays from inspiration and becomes a copy, plagiarism
I don't want to accuse you of that because I don't think there's any bad intent, I think it's moreso on accident, you probably just wanted to add recognizable references and make them as frequent as possible but you did it too much.
You should try to tone in down in future updates, pull yourself away from LiL and deviate from its plot, because the way it's going now, I don't think we'll be able to say it's only inspired and not a worse copy if it keeps going on like this.
