Hi! Thank you for sharing your thoughts on the game!
We don't have plans to add paths in the future. However, side quests are possible, since a few girls woulnd't be part of the main plot.
Minigames are something we want to add since the very first version, but we don't want to annoy the player with these. We are not sure when are we adding them.
We are adding dialogue options in v0.3.0 and future updates, since the lack of choices was one of the main problems.
Thanks for your comment. Good day!
