Nice aesthetic. Unfortunately it feels to me like there aren't really many meaningful decisions to make. Choices on upgrades between the run are not much relevant since with progress you will get to them anyway. The only meaningful choice I had was mid combat when I could select a mutation, but it was one, single decision per 10-15 minutes of gameplay.
It's an idle clicker that is separated into runs and it feels like there either should be more decision making during the run, like choosing which corridor I walk or the runs should happen automatically, periodically.
Overall the game feels nice, it's well done and does provide a dopamine boost, but there is just nothing that would draw me in for longer. I feel like I would be wasting time. But bare in mind I am not the target audience for mindless idlers.
