Managed to played in the browser and I actually enjoyed it, which I didn't think I would. It has that feel to it that pulls you in even with little actions on your part as you only use your mouse. I think more can be added to this with the same presence as fnaf if the developer wanted to add more to it. Could be more actins like a shock to get rid of moles digging near your drill or something like that.
All in all 10/10
