6 doesn't work in normal mode, 9 doesn't work in challenge mode, very funny
the game put me in a lot of scenarios where i feel like i couldn't have done better and i lost - bit more RNG heavy than i'd personally like, i'd maybe prefer if it got faster more than it getting more and more likely for you to inevitably die to rng
lost multiple runs to trying to mine and the pickaxe not working, i think it might have had something to do with mining on the frame that it swapped to the next number or something
there was some nice play with asking myself the question of "is it worth it for me to lower more tiles to increase my chances to get down further", but even when i feel like the answer to that question was obvious i would sometimes lose anyways due to 4 being selected 5 times in a row
