TV Ads factory!

Google Play:

New idle game from Airapport has satirical message about the state of the genre. The top idle games on mobile, which are published by big publishers, are essentially nothing more that the ads viewing factories.

Despite of the variety of settings: milk farm, sushi bar, growing plants, mining, crafting, producing, all these "vertical scrolling idles" have the same meaning under the hood: make the player view as many ads as possible (and often the screen controls, which initiate the ads are not event labeled properly). But, nevertheless, these games are in the tops of the mobile stores.

So, I decided to build a satirical game in the same genre, where you, as a player, make the people watch ads. The more ads your house inhabitants watch, the more money you earn, and the more special characters you unlock (you can see some of them on the screenshot).

You inhabitants will even require more ads to view (they get angry when the TV power is lost). Also they might get tired and eventually will fall asleep. Your task is to keep them awake by tapping on them or building some bizarre alarms (yes, the vibes of Engineer Millionaire will be here).

As the players other Airapport's idle games might remember, my own attitude to ingame ads is drastically different. The players will see the actual ads only if they press the button clearly marked "receive bonus after watching the ads". So, if you don't select to watch the ads, the game will be completely ad-free for you and still all the content will be unlockable.

Stay tuned for the release announcement!

Engineer Millionaire released to Amazon, AppStore and Google Play!

Engineer Millionaire is the 4th chapter of the steampunk explorers adventure. Now they have to build an ultimate factory and fill it with incredible machines.

The game is available on

To beta testers' attention

I'm really thankful to all the beta testers, who played the game since its earliest versions, gave valuable suggestions and helped to fix the bugs or translate the texts. You posted many good words in your reviews, which helped me go on.

It appears that it was only me who saw your wonderful reviews. Google Play hides beta testers' reviews from the other players. Now, as the game is released, I'd be happy if you made a public review. Here I explain how a beta tester can leave a visible review. You will help a lot!

Other steampunk idle games updated

Simultaneously with the Engineer Millionaire's release, we updated Steampunk Idle Spinner and 20 000 Cogs under the Sea. They've got characters and new, much more convenient and informative, upgrade interface.

You are welcome to check the updates and share your impressions and suggestions.
