The game is not as bad as people are making it out to be, it is only a few oversights that are easily fixed. Anyone who has used RPG maker in the past should know the issues in this game right now
1- Dialog for events are triggering before you have even triggered the event in question - like Camillas route. You say your GF should be at her house for the event...but she will not be there since you have not unlocked it yet.
2- Exiting the shop and aquarium put's you into walls. Simple enough to just move the warp point into the correct location, not sure how it happened though unless the map was different at some point.
Sure, these things should have been fixed before any kind of release since it is basic RPG maker tutorial stuff. One issue I do have though is I wish the 3d sex events were animated like the imagine on page 1...please animate them :'(
