The first day you play there are no forced ads then after that the ads are often and forced. Some of the ads are malicious and try to get you to install malware. This game it's self it's pretty fun but could use some tweaking for balance and progressing timing.

it's a normal free progression until you reach Tokamak. Then it stalls unless you pay.$$... a lot. unlocks and currency probably need you to drop $150+. it's hard cut. office upgrades make you wait a week or more while you try to earn to pay for the upgrades. office upgrade cost went from 67 to 285 (a multiplier of 625%) when the gain was only 25%. glad I never put a cent into this. was a fine waste of time in the beginning, now it is work. 3 days of free play is what I guess is normal.

Played for about 5 min, typical ads = progression style of gameplay. Multiple typos and text errors right out of the gate. They can't even polish the tutorial after years of this game being on the market, lazy money grab.
