Just wondering, is there a guide somewhere on how the points work?
Probably.
I couldn't find one nor a way to view our high score though. : /
Some rounds I had, I got over 900 when I thought I was lame.
I think that maybe the order you catch them counts.
What's sure is that the timer counts and if the Pokemon go off screen I guess. Whenever Pokemon went off screen, I made less points. And maybe, if you make 2 Pokemon collide, it may give extra points.
