Before the match
Okay, this time I'm shaking up the board with my speed!
Okay, Space Bunny, this time I'll show you my real speed of light!
Okay, try to keep up with my speed!
Okay, let's see if you can keep up with my fast tempo this time!
Looking forward to a fun match. Care to keep up with my fast tempo?
After the match
Okay, MIMO was tough, but I broke through the base and won. So happy!
My opponent was pretty good, but this time I broke through the base and won, totally thrilled and relaxed!
Okay, my opponent played great too, but going for the base worked perfectly this time!
Okay, this one really stings, but I'll definitely get revenge next time!
Haiku played well too, but I'm happy I captured their base with room to spare.
