Hello there! This is onpon4 writing again, except this time, it might come as a surprise to Emilio and Adman.
I have bundled what is in the Git repo for the Stellar Game Engine (SGE) into a ZIP archive to release it as the first alpha version of SGE. I haven't been able to talk much about this with the others, so for now, I've uploaded it to MediaFire. You can download it here:

In case the question is floating around in your head, I don't think another alpha release of the GUI is going to coincide with this alpha release of the engine. It wouldn't make sense right now because the GUI doesn't actually use the engine yet, mostly because there are still a lot of things missing and a lot of fixes to the interface itself needed. But I'm releasing this early alpha of SGE so you can see some of its progress. Already it is powerful enough for a decent Pong game, and a basic example showing off some of the features is included.
Cheers!
