The problem
If your game doesn't open in Arch Linux, try closing steam completely, and launching the steam command from a terminal.

killall steam steam

Then try to launch the game and observe the output.

If you see something like the following error, this guide might help.

./Loop_Hero: error while loading shared libraries: librtmp.so.1: cannot open shared object file: No such file or directory
Possible solutions
First, install the librtmp library with the following command.

sudo pacman -S extra/librtmp0

Try to run the game. If the problem still persists, check the installed libraries.

ls -l /usr/lib/librtmp*

In my case there was only a /usr/lib/librtmp.so.0, but the game expected /usr/lib/librtmp.so.1. Creating a symlink fixed the issue for me.

sudo ln -s /usr/lib/librtmp.so.0 /usr/lib/librtmp.so.1
