Looks fun—I just tried opening it on a mac and it only works with 32 bit systems. Which is >4 years out of use, I think. I suspect this would be a huge challenge to build, but I thought I'd mention it.
That is weird! I grabbed the demo zip from here, on itch, and I’m running my device on Sonoma atm. It might be something to do with the intel vs silicone chips, maybe?
Actually, it’s not related to the OS but to the chip. The game only works on Mac M1 and above, but not on Intel Macs (because I only have a m2 to build and test).
As armatures said, I think it would be a big challenge to make it compatible with Intels chips :/
