Author you’d been making mistakes with regards to the word “shuttered” it should be “shuddered”
Shutter = something on a camera
Shatter = break
Shudder = trembling/tremble
The only major problem is the updating stability. Hoping for regular updates. Wish you luck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
