small update — Dream of the Star Haven Steam update #837358

• the main skybox was overwhelmingly white at the bottom which threw off the overall aesthetic when looking down, so I've mirrored a section of it • a few visual tweaks to sokoban parts • reverted the level-entry platforms to use 3D locks and stars as the vector images weren't working well for those. I'll continue to refine the game-wide balance between using 3D props vs 2D vector images
