Mega Dystopia Micro Architect v1.2.1 version release includes the following updates:

• Option to flip d-pad navigation direction.
• Bugfix for instances where players were able to build buildings on top of each other after gaining the grid size perk.

Both items were reported/requested by the players, and I'm very grateful for that. If you have any requests, ideas, or other kinds of feedback, I would be glad to hear them!
