I hope the Switch version gets a price cut to make it more fair.

First and foremost, the only way I've found to actually close the program is to Shift Tab and force it closed. If there's another way, please let me know. Secondly, once you purchase the soundtracks, you must install them from your Steam library(?), which then makes them selectable along with the game options through the launcher. HOWEVER, selecting them opens the directory containing them, not a submenu within the launcher itself. and should you decide to play them, you're doing so with the menu music...

This game plays great on the Steam Deck. Just make sure you set your "Screen mode" to "Window" and not "Borderless" and not "Full Screen" to fill the screen. They must be mislabeled. I am not sure what "Rendering Scale" does because despite what I set it at: 1x, 2x, 3x or 4x there seems to be no difference. Also as Pootwaddle pointed out the way to play the music from the sound track is not intuitive at all. Besides all of that, the game looks great, controls great and sounds great on the Steam Deck....

Are there any fancy filter in this collection?

1.) Which console are these games (ROMs) from? 2.) What else is planned? If not "secret" release the names of more to come, or hopefully to.
