Becone blurry and pixel change

Hey Guys;
I made a picture in 34×32 pixs on Aseprite and the I exported it 600% bigger for my twitter. First, when I upload it to twitter it become blurry and then when I zoom into the image with a 1 pixel gride, I can see each pixel is made from 6 pixels. Should I change sth from export setting or tools that I used?!

if you are gonna export you have to select the twitter export option, theres a checkbox for that
