All things considered, good game and great time-killer. Easy to quit, without having the commitment of riding round like the online multiplier games.Positives - Game is very addictive in its progression. Once you get down few levels, gets very strategic. No in-app purchases required for advancent, but the few there are, and inexpensive and definitely worth the $2 bucks.Negatives - controls are as accurate, causing you to lose resources which isbfruatrating. Most importantly, the "emergency/bail out" feature (brings you to surface but loss of all resources) that happens when selecting ladders W/ a zero balance need an additional level of confirmation. Quick clicking has caused too many accidental confirmations.

I love playing this game! It kills time and doesn’t take a lot of thinking, it’s pretty mindless (meaning when I have had a stressful day I can play it and not make my mind think). Now I am to the point that I have unlocked the Megan elevator but it disappeared from the garage. I have installed 4 or 5 air vents each one is maxed out right after purchasing it and it doesn’t help with the depth I can go. It’s like it says it’s maxed with the rating of a new level one one. Also, there aren’t anything new and cool to use the money on in the shop of the app. I am digging for money that I can’t spend on new tools or upgrades! This makes the game even more unchallenging. The confirmation check and x don’t line up with pushing them, I have to cancel by clicking the check mark and confirm by clicking the same space over on the game field (apparently this is super hard for others to figure out and kinda annoying).

best phone game i’ve ever played, hands down. the graphics are maybe not as flashy as some of us are used to but the game design is perfect. it’s random but still takes a lot of strategy and it’s so addicting that it’s almost troubling. it’s a great game to get frustrated with but not be able to put down and for me at least, it’s been easy to put in way more hours than i’m comfortable sharing here. OH! ONE THING THOUGH! for developer : whenever i buy a sign, when i go to place it somewhere, the game freezes up and i can’t do anything until i close out of it (losing all progress since last save) and reboot 🤔 major bummer there but still 5 stars 🏆

I enjoy playing this game repeatedly. It is relaxing, yet presents problem solving different configurations. It closely resembles Gem Miner:Dig Deeper which is no longer available. My one critique is that some areas never stay revealed after I have been there, especially the long columns of 3 open spaces, and the spaces that appear to be bombed out. It would be nice if that were fixed. I also lose my motivation to continue after I get the full drill. Getting the statue is anticlimactic.
