Time for this account to showcase its maxed walls. All 4 upgrades done/upgrading, so I’m now back to having only lab remaining.
For both of my accounts, I upgraded sweepers first because it was more useful, but it took shorter time. Knowing that, I should’ve started bomb towers first because then all my upgrades would complete in the shortest amount of time. With lab still requiring more than 7 months (220 days) to max, I’m not too concerned, oh well
