thanks for your comment. You are correct. I should update the demo and I will soon. I was busy with fixing the prod version I totally ignored it.
Compared to current demo, production version is much more stable and optimized.
The game runs fine on any modern android smartphone.
This game was only a simple simulator. I'm working on much bigger game, fareast, at the moment. Yes that game did suck before, but I have re-worked everything from ground up.
Plan is to have a complete city, but that is gradual.
Check that out and appreciate your comment on that as well.
I will update the demo within this week :)
