I finally managed to get it run on Manjaro Linux!
I only missed 2 dependencies, which are in need: to run Construct 2 games!
- libnss
- gconf
I installed these in the package manager, and then worked!
The link that showed me the way:

Have a great time!
Edit: months later, I switched to Pop OS.
Now, (sudo apt install) libgconf-2-4 was all I missed.
Not libgconf2-4, that wasn't working for me..
