If a developer wasn't around or willing to recompile and test their game on x64 to support Catalina (which dropped support for 32-bit apps), then it's not surprising to me that they are also unable or unwilling to recompile and test and support the game on M1 ARM chips.
I have used this service to play a few different games which I have licenses too where the developer no longer supports Mac; oddly this seems to have gotten worse with M1 chips.
