Any suggestions will be apprecieted

I just finished the game with a friend and I am missing 5 of the 12 achievements (2 of those are for completing the game). I have also died more than 5 times and consumed more than 10 cigarettes and those have not counted either. The level 37 achievement also didn't unlock which is weird since all of the other level related achievements worked fine....

I gifted my bruzz the game and multiplayer is bugged as ♥♥♥♥. FIX IT.

I have screenshot proof if needed thank you

Me, ^^ and Kur*a bóbr beat the game on sigma and none of us got the achievement for beating the game. I should have all achievements except get tweaked...
