Pen Dig ٤+

Needs to have more then one mine when one reach rock bottom the next mine opens up (unlocks), this way you can have more then one mine. Then the mine can refill it self as once is Finnish with that mine 1. As working on the second , then when down the second the first would be ready to start new from top of dig.
With ads now a days any free app is loaded with ads very part of the game with can turn off a lot of new customers for the app, just make more game with as minimal ads as possible and a chance to pay for “no ad”. If your going to use ad then why not let the customers that want to download be able to play there 1 or 2 second video on their device instead of the ad, the ad will still play in the back ground, everyone is happy.
You can list (buttons) all your other apps in all your apps so one can go to and from each of your own developers own apps.
In app purchases can help.

so when i get games like this, i tend to fly through them and that held true with this one. not 15 or so minutes in, i have maxed the pencil size and finished the city, but i haven’t maxed the stamina or income (i like the max everything out before moving on) and after about 200 meters, the game just crashes. i don’t make money, the pencil glitches INSANELY, it stops breaking any material, and just glitches for about 100 meters and then the app crashes. my phone is up to date. i had this issue on my ipad with this game as well. i’ve tried it on and off wifi and i still continue having the same issue. i’ve deleted and redownloaded and restarted about 4 or so times and it still happens everytime. also, this games ads? every minute max you have to watch one. i’ve never experienced a game that plays SO many ads. and there’s a feature where if you don’t have enough money you can watch an ad to upgrade for free, but even if you have the money, after every upgrade you have to watch an ad anyways. really frustrating. i don’t understand why it glitches SO bad it makes my whole phone crash. really obnoxious honestly cause the game would be much cooler without the overwhelming amount of ads and the constant crashing. i literally can’t even make money anymore because it just doesn’t work, nothing breaks, no income gains. so ridiculous. really disappointing. this game had a lot of potential but let me down pretty quickly honestly.

This is a rather silly game. It's funny how you have to use a pencil to drill down.

However, every time you upgrade, you need to watch an ad as well, which can get tiring.

Advice: have patience
