I tried Loco Roco and I didn't like it: I don't know if I should try it again, maybe it was not the right time, or maybe it simply isn't for me.
I played "Patapon 3" and I enjoyed it, but I still remember a VERY frustrating part in a later chapter (I believe I never or rarely found a most frustrating section in a game). After that I tried the previous titles, but (maybe it's just me) I found the rhythm more difficult to follow, I don't know if there were improvements in the gameplay of the 3 comparing with 1 and 2 (of course I'm talking about psp titles, not the remake on Switch).
