i cant download game

[somethings]

when i trying to download STGC, progress bar stays in 0% and closes after time. i dont see Slendytubbies Guardian Collection in my C:\ folder

If you cant download it through launcher, then I recommend you to download it in its zip form (the entire game build in its zip form)

where i can get zip?

You can ask for it in the official discord server if you want.
