To get most of the achievements all you do is do a full playthrough. Each achievement is chapter based. I recommend it since it's a entertaining story and the creators put their effort into this give it a chance.

If you're only here for the achievements and are just gonna skip everything use your LMB [Left Mouse Button] instead of space bar like I did playing the game. This achievement is attainable by clicking your LMB through the story and racking up a hefty 1000 clicks. The game will update and show you how many clicks you're at every 100 clicks.
***You can use an autoclicker or easily make a bind that clicks for you it will be much faster unless you want to test your finger dexterity 🤠****
