I recently contacted the developer about this. He replied that the only reason he hasn’t released a native Apple Silicon build is that he doesn’t have an Apple silicon Mac yet. I was tempted to fund raise and send him one!
My understanding is one can build a Universal app on either platform. Debugging the Apple Silicon side does require an Apple Silicon Mac but a well-developed app with a constrained feature set might "just work." They could make a Universal build and offer it as a beta to those who wish to try.
I don't know where they're located but a refurbished Mac mini from Apple is $589. AWS EC2 M1 Mac instances are ~$16/day ($0.65/hour, 24-hour minimum).
