Hmm..🤨

I'm at the final stage and need to clear it, but I don't think I'll have enough time..ㅜ Has anyone played this game before? Do you have any tips..? I have about 6 days left and I'm still level 11.. Can I reach level 20? I really enjoy the game itself because I like merge games! But it's a shame the time limit is so short…ㅜ
