possibly just because my screen is 2940x1842 at 13”: the font is TINY, so at no point in the game was i ever able to read my score or timer. still beat it tho, just had to “feel” when the timer was going to expire
you should normalize your movement vectors. as it stands, pressing right moves you one unit per time, pressing up moves you one unit per time, so pressing the up-right diagonal moves you over 40% faster at 1.414 units per time!
