very solid concept, some of the achievements aren't really feasible as of rn (such as getting a year of max lifespan or the 2 months/s aging speed) but Ill assume (and hope) that's just because the game isn't finished. Would love to see this more fully fleshed out with more ascension upgrades and/or more prestige layers. (also one more small change I would include is that if you click the commit sudoku button, you should get the life points you would've earned had you died naturally at that moment, since as of now the button is pretty useless considering you can still buy upgrades while the life goes on
