It is atually cool... It must be a huge effort to write with multiple variable, in the game 'dead dating' there is something similar, but you are open to interact with everybody during the main plot and only after it is closed the player is free to engage in a relationship among the characthers that the MC reached the 'in love' status... I thought yours would be similar, but route games are also awesome, the important is the quality of the story ;)
