Download it from the download section!
The launcher will always check for updates without you having to re-downloading the whole game every time there is a new version of it.
All new versions will be announced as "News" from now on.
The current version that can be downloaded via the launcher is alpha 4.6 and have the new procedural mesh editor that can be used to create more complex levels more easily.
I will make tutorials for it later on.
It will not overwrite files in the textures and sounds folders ( It will only download them if they are not there ) so you can replace the sounds and textures with w/e you want.
