My level won't go up!

My level really isn't going up! Is it because of the balance between deliveries and the story? I'm still level 6. I feel like I'm playing bit by bit, though. Doing things like rebuilding the village too. If my level goes up, will the board expand? I want to clear away the cardboard boxes around me... My backpack is also stuffed full... Maybe I should increase my backpack capacity first... The board is narrow and energy runs out quickly, and I'm stocking up on items without receiving them immediately... It's tough 😂
