Ah, thank you so much for the input!
I'm actually working on an updated version with better graphics, bug fixes, and typo fixes so this is a big help :D Plus, feedback is always loved! You're really livening up the dead space in the comments area and I'm very, very thankful for that as well.
As for the endings- I actually have a walkthrough up over here but it seems like I totally forgot to link this page over to it. Oops. I'll get to fixing that as well. (And just in case you want to get through without direct advice, don't worry, there are also hints there to help you figure out the other endings yourself! Self-discovery has lead to most of the feedback for this game elsewhere :3c )
Anyway, thank you again for your comment, interest, and love for this game <3 I hope senpai notices you soon! ^^
