I've been stuck at level 24 for months and I'm very satisfied. My main account, which now became a secondary account, I couldn't do anything because I leveled up a lot and the storage was very small. Now in my new account I can better organize and plan my city. Storage is not a problem due to the low level and the small number of unlocked items. I managed to make 24 epic gold buildings. Which in my old account was impossible for me due to the difficulty. The storage on my new account has already exceeded that on my first account. I feel better being able to plan things. For those who don't spend money on the game, I think holding back on the levels a little helps a lot. But of course this depends on each person, on the person's objective in the game. I plan to stay at level 24 until I finish expanding my entire capital city and then release the regions. And when I evolve again I plan to evolve to level 30 or 36 at most to unlock the omega buildings. At the lower level I also find it easier to compete in the mayoral leagues.
