Assuming this is a work-in-progress, it has potential. It's perfectly playable on a Quest 1. The physics is well-done; not ideal - but well-done. After selecting a four-legged stone structure, I smashed out three of the legs - and it didn't collapse until I smashed the fourth. But ... it's a nice environment for smashing things.
Here are a few things that I would see improved:
The interface that allows you to select a target is ridiculous ... it's a massive panel with dozens of buttons - and it's far too easy to tap the wrong one, since the buttons are horizontal, and you have to reach over some buttons to push others. Better to replace all of this with a selection wheel or something similar. Anything that reduces the number of buttons on the display.
In addition to the obvious sledge hammer, the game provides other tools, including one-handed hammers ... and some sort of machine gun. I couldn't get the machine gun to work, and there is no tutorial. I was able to pick up the gun. I was able to connect a clip of ammo into the gun. But when I fired it, all I got was a clicking sound. If there are more steps to this, there shouldn't be. Ditch the ammo clips. This isn't a gun simulator; it's an interface for smashing things. The gun interface should be no more complex than picking up the gun, and firing unlimited ammo at whatever you want to break.
At this time, the only audio appears to be the selectable background music. When I smash things with a sledge hammer, I want to hear the appropriate sounds, whether it's stone, glass, ceramic, etc.
