I tried Dome Keeper these days and then this. I played 5-6 hours with both. Based on this, I liked Wall World much more because of the following:

• I like the art better.
  
• I like the soundtrack better.
  
• I found it more diverse. After 5-6 hours, I was bored with Dome Keeper, but I would continue Wall World.
  
• It's much cheaper.

Dome Keeper was the first and I'm not saying it would be bad, but I think this otherwise obviously copy of its core mechanics was surpassed its predecessor.
