why isn't this 1 step from the solution? the block just passes over the target. https://imgur.com/a/NmWj4ZL

I am using OSX 10.14.6. The white tiles are "not stable" and appear to slide across the green background when the crate is moved along them. It is not clear where the green exit tile is. Also on the simple laser level the game crashed or the graphics "jittered" ....

Why not on Windows 7?

I get the splash screen and a tiny bit of sound. Then the game just stops and reverts back to the OS. My specs are all above the requirements.

Hello, I received the game as a curator copy so maybe it's related that the success are not working. But I think that I already had success from others curator copy so I'm not so sure. I tried to use the login/create user feature to create a user and see if there are other custom levels but I not think the login/create user work because it look like it's doing nothing. Cheers...
