This bus game seems the hardest..

Eek! It must be so upsetting that Kejinning's bus formation is super tough! :( Matching colors can be surprisingly tricky, but our Yangyang will cheer you on! >_< You must have worked hard just now, so you should eat something delicious and regain your energy! :D:D

The graphics also make it feel harder.

This isn't hard, it's designed so you have to watch ads to clear it. There's no real solution. You need to watch at least 5 ads just to clear the first round, and if you're unlucky, it might take 10 ads lol. I'm doing it now for a coin-collecting quest, and I'm going crazy from stage 30 onwards. I'll probably only do up to stage 50. Any more would just be annoying.

Usually, after watching an ad, one has to be opened to break it.

The mandatory ads are really annoying.
