Too many items!

If you stack 3 of the same kind, they combine and create space!!! My heart coins combine too.

Looks like you're collecting them for a merge 👀 You might need to organize them one by one ㅜㅜ there are too many things out... I intentionally don't pop bubbles when they appear, set some aside, and then pop one bubble when I've collected 4 to merge them..

Also, considering how much land you've expanded, your tree levels seem a bit low. For level 1-2 trees, if they aren't for quests, it might be good to just use them to free up space! Harvest and clear out dead trees quickly too.. When harvesting trees, if you don't have board space, you could have your dragon harvest them and then keep the bubbles unpopped for later.
