The 2 Loop

After 6 months this is my new puzzle hope you have fun!

Rules:

Draw four 2x2 boxes in the grid that don't overlap, and fill them with the digits 0-3. Digits can't repeat in a row, column or 2x2 box. Cells that aren't in any box are empty. Draw a loop which travels through the center of cells by moving orthogonally or diagonally, passes through every box, doesn't branch, and doesn't visit any cage or empty cell. The loop acts as a 2-line; the loop can be broken into non-overlapping contiguous groups of cells that sum to 2. Adjacent cells on the loop that are in the same box must be orthogonally connected, while adjacent cells on the loop that are in different boxes must be diagonally connected. A digit in a cage indicates how many cells aren't on the loop in the box the cage is in. The red cage has a higher digit than the blue cage.
