I liked it. It's basically a game of taking the smallest risks as there are a lot of uncertainties. I can't proof it, but I'm pretty sure you added some wave function in the amount of matter that is dropped so sometimes I'm too big and sometimes I don't have any fuel left, which definetely varies the gameplay loop. The most scary/unfair/memorable moment in the game is definetely when you have no choice but to stand near the clear ceiling and anything drop on your head at any moment. One must wonder if there isn't anything a developer can do to prevent such a situation by adding indicators, but I actuallly kinda like it + I have no idea what kind of indicator could elegantly display where danger might be hiding in the darkness of the infinite above. Sometimes there's an actual impossible scenario, which need to get ironed out
The art was simple which fits the game, but in the end is still simple. Giving your game a bit more of an identifyable look can elevate the gameplay even more while staying decently simple. The saw blades look great.
BTW, I added some shameless self promo at (edit: near) the top of your leaderboard, remove it if you dare! TUV is me too
