Ratings and reviews

Instead of not allowing the upgrade buttons to be pressed when you can't afford an upgrade, it takes you to the premium currency shop, and all the high cost items are on the side with the upgrades. Therefore, if you spam tap the upgrade buttons, you may accidentally try to make a $50 purchase or spend diamonds without knowing and without delay. Luckily, Android requires confirmation before purchasing. I find this sneaky and underhanded. Another review calls this predatory, and I agree.

Played until floor 5000 and I've gotten the second to last upgrade on all excavator parts. The roadblock I hit is massive and will probably require me to play for months just to get 500 more floors. It feels like the ingame scaling needs some attention, math-wise, and the game lacks an incentive to continue playing (I.e a form of reset/ascension to actually make progress feasible.) overall this *could* be a good idle game, but it's current state makes it a *game over* for me.

It burns the phone! Well, NOT REALLY, but it increases phone temperature significantly, even when played offline, with graphics set to minimum. This seems to be always the case with game this genre, with hundreds of 3D floors. A bit repetitive and it doesn't run when we're not actively playing (not really an idle game). I heard it has aggressive micro-transaction, but I'm still enjoying it f2p. Has GPlay Achievements, cloud-save and playable offline. Not the best imho, but still worth playing.
