This game is ALL ads. Not just “watch an ad to upgrade faster” but “watch an ad to progress the game”
Decline the ad? Watch one anyway with the option to skip 5 seconds in.
It is a questionably boring game concept to begin with (build a machine, perform prompted actions to “manufacture” goods, hire an operator to do it, then sell the products to people in line) but the ads make it unplayable.
Overall it’s an average “minimum wage job simulator” rendered even more useless by advertising.
