Played many games like this where there is clearly a MAIN girl. Cece is the main girl of LoF, everything leads to her... and of course its obvious that she is the main girl first hand. (even if youre not in a realtionship with her she is the mainpart of the game)
Some other games has this trait to... melody for example, and give you the option to go for "other" girls, but the realtionships with them, and the characters are not that deep... Iam ok with that if the main-LI is well made and the realtionship too, and thats the case in LoF.
The other girls are very likable too overall, but yeah, in comparsion to Cece, her path and everything about her is much deeper... but Leap of Faith is the story ABOUT Cece not really the MC i would say, tho its kinda naturally here.
And i would say... like everyone, the DEVs although have their "favorite" in the games they are devolping... Drifty sets his heart in this game (for personal matters, cause its in many points a story of his life too) and its displayed very much that he wrote this story for this very character called Cece. But i think he did a great job to make the other girls very likeable too, not many DEVs can pull that off, in fact for now i just only know 2 other games with more than 2 or 3 really interesting girls where i want to start a relationship with them not just out of curiosity. And where the realtionships are made really good with more than just one girl... its not an easy thing to pull off and make it work in a game. Drifty made it good, not perfect, but good enough... and now we need statisfying endings to wrap things up real good. Hopefully he can manage that, but iam confident that he will do just that.
