Gotta love these Itch notifications sometimes.
It's not necessarily abandoned, just on a temporary hold. Largely due to the financial investment nearly doubling the return. Once I have a second system up and running, it'll resume development. Likely slower, but resuming nonetheless.
As for the link itself, I wasn't aware it was down. I'll throw another one up in a few here. Apologies for that.
Edit: Should be working now.
