I really loved this! I at first thought the integrity life meter was based on me not contacting the people with my radio comms having issues but I realized quickly I was trying to drill through rock. I really like the little funky tune that plays when you're close to being done.
The art style was phenomenal, I really loved the aesthetic you went for, it really made it feel unique and cool.
The gameplay is also amazing, it's simple but works great! I think you have an excellent base for either continuing or working on something new! Every upgrade felt meaningful and it feels like there wasn't one that was lacking.
