Yes, that's what I've done, but:
- You can't download the 'unstable' version directly from the devlog, you have to first go to the game page, and then choose it correctly in the downloads section
- This will quickly get messy if I have more than a few versions (and even more if I have Mac, Win and Linux builds)
I think it would be good to have the option to have per-post uploads, just like we can have per-post screenshots that don't interfere with the game page.
