In options, you can put all "text speed" to max.
Then Play & just hold Left Ctrl, both achievements of this game will pop within 2-3 seconds!

You will unlock this simply by completing the game. If you don't care about the story and you just downloaded this for an easy completion, you can just spam the spacebar OR if you don't want to do that you can turn on auto-play by clicking on the play button, and then leaving the game to idle (this will take longer, but at least you won't have a sore finger by the end)

TiCyrillou says that you can "Put all text speed to max & instead of spamming spacebar, just hold Left Ctrl, both achievements will pop within 2-3 seconds! "

I can't confirm this since I have deleted the game but I am assuming that what he said is correct.
