I love this game, but I noticed ,after upgrades ,energy spent on blocks increased. What started with 1,2,3,&4, is now up to 13 to 50....I built my energy to 800# recieving 550 per hr. Now I can only get 15 to 20 blocks & wait an hr to move forward. Talk about sneaky to get money. I'm on retirement income. Where are the needed peach for laboratory jars. I gave you five stars, but you get 0 if I leave. Ads should pay for my time, as this give nothing back for my time watching them. Butt you get paid by my time watching them. Let's get real on the next upgrade you want or I'm outta here. Sorry.
