PS$ - TAIKO NO TATSUJIN

If i remember correctly, there were some additional Play-Modes on the Taiko No Tatsujin PS4 Demo.

Now after i bought the full Game + Drum i was upset that theres just ONE playing Mode? The normal "Play the Song"-Mode.

Why can't we (PS4 Players) also have the Mini-Games like the ones on the Nintendo for example?
