The wording on the store page threw me a bit. It's obviously buy 2 or more games
then get free standard shipping + Cytus CD. For some reason I just read it as free shipping on those games.
I ended up buying Deemo for just under $22 after shipping anyway as that's just a fantastic deal for such a great game. I already own the digital version on Switch, the Asian special edition on Vita, NA Vita digital version, and the base game on iOS.
For the unfamiliar, Deemo is an utterly relaxing, self-paced music rhythm game with a unique story and gorgeous music. The success conditions are rather generous IMO, but that's not a bad thing. The Switch version feels like it unlocks stuff much, much faster than the Vita version. I feel like I had to grind so much more in the Vita version(s) to unlock stuff. I think the lessened Switch grind is a good thing because it contains all the DLC for free now and moving forward, so there's a lot to unlock. As a DJ Max player, I think the pace of unlocks is wonderfully generous in Deemo. Not too much too soon, but enough that you can come back after a few weeks/months away and somehow unlock something relatively quickly (as was the case for me today - a new song and a new book (album) of songs after just a few song plays!).
Admittedly, I haven't "beaten" the main story of any version of Deemo despite owning so many for so long. I just enjoy taking my time and playing the songs that relax me or put me in a nice groove. I treat each new cutscene unlock as a nice surprise, but not as a goal unto themselves. In other words, play the game, relax, get emotional and/or groove, and walk away feeling good
