The theme and art surrounding this event is super cute, but I'm not really sure about the timed nature of the tasks?

Hopefully the additional quests will even out the maths on this, but I really hope that it works out so that players aren't expected to lose sleep to grind to the final tiers. Expecting commitment from players to reach the higher scores is one thing, but for people to potentially have to lose sleep over it would be a pretty unpleasant expectation.
