A 2 hour commute sounds like torture to me. I work from home and I would go crazy if someone forced me to stay away from my dogs for that long. Especially without pay and just for getting to the damn job.
When buying an early access product, especially at that low a price, there's always the risk of the dev not being able to mantain it as originally intended. That's fine.
If you do find time to work on it: A smooth, polished experience is worth much more than a ton of new features anyway. Take care of yourself :)
