Here's the puzzle I made for Sniglett for a recent Twitch Train event. I also ported it to PuzzleTV for extra interactivity (the PuzzleTV version uses cages instead of shaded cells for the Nests).

RULES:

• Slide & Seek: Move some shapes orthogonally and draw a line through the path taken such that:
  • Every cell in the grid is either a shape or path.
  • After each shape is done moving, no two similar shapes (meaning, two diamonds or two circles) see each other in the same row or column (different shapes block the view).
  • A number in a shape gives the number of cells that shape moves.
• Oyakodori: Two shaded cells diagonally adjacent to each other are a "Nest." For some nests, only one cell is given and the location of the other must be deduced (the second cell must be diagonally adjacent to the first).
  • All circles must end their movements in nest cells. Each nest must contain one black circle and one white circle.
  • Nests do not affect line of sight for Slide & Seek rules (meaning, a circle in a nest is still "visible").
• Diamonds may end their paths anywhere in the grid, and some diamonds may not move at all. The red color is purely cosmetic.
• No shape's path can intersect another path of a similar shape (including its own). Black circles' paths cannot intersect with any other path. However, white circles' paths may intersect the paths of red diamonds. Both shapes must go straight at each such intersection (an intersection cannot be at the start or endpoint of either shape's path).
• Each white circle must cross at least one red diamond's path at least once before reaching its endpoint.
