Here's how to make and play a current build of Aquaria
. I'll assume you're starting with the Steam version because that's how I recommend buying it these days. When you're done, you will have a build that is more up to date than any official release. If you're on a 64-bit distro (as I think most of us are these days), then the resulting binary will be 64-bit native.
Use the Linux version of Steam to install it. That will get you a 32-bit version that needs Steam to run. We'll then make a copy of the game, build False Genesis' Aquaria Clean
repo, and put them together.
Assuming you're starting from the Linux Steam version, here are the exact sequence of commands to get it done:
cp -r ~/.steam/steam/SteamApps/common/Aquaria ~/aquaria
git clone https://github.com/fgenesis/Aquaria_clean.git
cp -r files/* ~/aquaria
cp -r game_scripts/* ~/aquaria
cp aquaria ~/aquaria
You can then launch aquaria like this:
On my multilib Slackware64 14.0 installation, I've tested it as far as getting the shield song (about 5 minutes in). Everything up to that point works.
