It's here, finally! And it's a big one!
Thank you so much for your patience, everyone! As promised, the new update contains the following:

• Massive Engine Update. Probably the main issue many people were experiencing was a low framerate. The new engine should significantly help with this problem and make for a much smoother gameplay experience!
• Bonus Story. Reaching a certain ending now unlocks an epilogue containing 10-20 minutes of funny dialogue and brand new eye candy!
• Route Shortcuts. After unlocking your first ending, you will gain access to the "Shortcuts" button from the main menu. This lets you skip to a specific ending, provided you've already seen the necessary scenes from the common route. See this guide for more details about how it works!
• Fixed achievements. The previous update introduced an error that prevented achievements from unlocking on Steam. This is fixed now, and your previously earned achievements should come pooling in as soon as you start the game.
• Minor edits to maps and cutscenes
• Fixed one(!) spelling mistake
• Many other minor improvements
