Kindly remove closed quest like wen christmas? and $moca public sale code contest. and have Daily/Weekly Quest with a reward coins or pixels depending on the difficulty of the quest. Also have an interactive npc for that quest. I also suggest upgrading of ability like planting many plot in one tick of seeds as wells as the watering can upgrade to easily water crops something like that

Add weekly games where all of players can particpate ex. finding something hidden in terravilla.

Add a dashboard with daily and weekly quests. The rewards should be points that can be used to purchase various common and special prizes. For example, for Quest 1, it could be 5000 Popberries, 2000 Butterberries, 500 Scarrots, 5 SAP, and 10 Bombshells. You can submit the items needed to complete the quest.This will help the Pixel's economy circulate quickly, and the number of points earned will depend on the difficulty level of the quest.
