Reached Level 30 in Playo!

I took this screenshot a few hours ago, but I felt it would be a shame to just let it go, so I'm posting it. From level 1 to 19, my level went up incredibly fast, but I was stuck between level 20 and 29 for several weeks. Finally, I broke through level 29 and reached level 30! It wasn't that I was stuck for an extremely long time, but I did spend more time than expected in the 20s. Seeing people who are level 100 or even 80+ makes me feel amazed and a bit envious, lol. Did leveling up used to be faster when the attendance check system was still around? I'm not really sure since I started playing Playo seriously after the attendance check was removed..
