I bought the game and tried to play it, but the screen looks like this. I'm on a Mac running Yosemite.
This behavior is new to me, currently I'm discussing this with other developers. It might be a bug in the framework itself.
Can you trigger this bug or does it happens all the time? Even in the main menu?
Only if you want to, please test another game located in the launcher, like Nano Space, to see if the bug appears there too.
Nano Space plays fine for me, and when I first open Ore Miner 2 it displays everything fine, but as soon as I load a world it goes all weird like in the picture I posted, and if I escape out of it, all the menus look like that too.
I double checked the render engines, nothing special, nothing which could crash. Nano Space uses much more complex shaders and it works too. Based on the results you send me (textures wrong overlapped) it' definitely not an error in the game itself. To find the thing which triggers it I need a Mac to test it on. If you have the time and interest to help me finding the error I can send you several copies, each with code parts disabled, to find the error this way. However the chance of success is low since the error could be everywhere.
I apologize for this issue.
