Now the game looks a bit better, also music sounds nice. Level 6 track reminds of Super Mario Bros for some reason, but on this level it takes a long time to wait for the platform in the beginning. Camera adjustments on some levels are good.
I think, that it would be nice to add a sound of jump and change the sound, when you fall on the floor and make it a bit softer. Maybe, some effects when moving, like particles coming from the bottom edge of the cube.
