Is shapez a Unity game? I ask this because
Unity games from 2017 never work for me.
I also need to know if the game is offered
as a 32 bit version before I buy it. *?

Kind regards

No, it is not a Unity game. But, I dont recommend to buy it here. Its locked to v1.0 since... forever But there are updates and even a DLC available, just not on GOG... Apparently, you can even play full version via browser.
