Thanks a lot for your feedback! You are right it has issues with the game over because the game (even the quick-fixed version) is not finished. This was mainly because it was our first game jam and we did a terrible job at managing our time. We are planning on updating a finished version later on so if you want you can follow the progress on GitHub if you wish.
Also, thanks for letting us know the bugs you encountered, we will work on them for the finished version whenever we have time.
One last thing, you probably "finished" the game as in you didn't die. The plan was to make the game finish whenever you finish the visual novel game. However, because of some sloppy code, you are not showed the last frame from the visual novel and are directed to the Game Over screen directly. This will obviously be fixed but you at least you know that you didn't die. We will add a health bar for this matter.
Your feedback is greatly appreciated! It really does warm our hearts to read such an enthusiastic review. Thanks!
