my office chair was broken
but i think i fixed it
it kept sinking down and i thought it was because i gained some muscle and bones lately
but no, i took it apart and some rubber gasket around the piston was ground to shit
and i've found a suitable replacement
why i only think of doing this after 4 beers at 0030 is a mystery
i watched a playthrough of the belgrade level in peripeteia yesterday
turns out the reason why i struggled so much is because at the start of the level i accidentally fall down without dying and basically skipped a whole section of the map
