Hello, I would like to 100% this game (get all achievements) and i have all of the achievements except for these two and the 250 potion one. How do i get these achievements?

how do you trigger this achievement?

upon launching the game, steam returns an issue about needing a .exe file to launch the game. When launching the corresponding .x86_64 file, I get until the "made with unity" and the "heavy duty tape" frames, but it crashes immediately after. The mouse pointer gets huge too. Steam then returns an error message about not finding an .exe file...
