This is really creative, I laughed a lot at the billionaire using the ads for getting money as well. Nice game!

Nice idea with an ant farm style of appeal. I just liked watching the transports going back and forth!

Cute little diversion; it's all about balancing your resources.

I do like how subsequent purchased increase in price, but unfortunately your advertisement income scales with ad purchases.

Since the increasing cost of ads somewhat cancels out the ad income rate, the best strat seems to be to simply spend your opening time buying nothing but ads, so that you can just blast through the early phases of every other purchase.

I just noticed that I left the game running unattended for about two hours now, and the path to the summit seems to be about halfway done. I hope that's not an indicator of game length.

I really liked the idea, it runs really smooth too. One issue is not knowing that you have to buy ads to make money at the beginning.

Pretty cool game , I managed to build the escalator. Pro tip: invest in ads early. The animations are nice and smooth and art is minimal but gets the job done and fits the game well. One thing to improve is probably the pacing, at one point half way you cannot afford anything and just need to wait. The concept is creative and unique , and fits the theme perfectly.  Good job!
