New for Steam Version

If you've played previous versions of this game, there is some additional content for the silver/Steam release.

One puzzle/plot element has been altered on Linds' route

A new CG+epilogue has been added on the final route

The UI has been replaced to be more fitting to the theme (thus the 'silver')

The engine has been upgraded to a new version, along with a lot of adjustments to controller handling, graphics fallbacks, save game proofing, and other behind-the-scenes stuff that you should not particularly notice. However, because of this, old save games are NOT compatible with the new edition.
