This is a collaboration with Isamook - the estimated difficulty is 4.5★ and we hope you enjoy it! :D
Thank you everyone who tested this! Especially Myxo, for helping us fix something in our first draft.
• Nuri-Maze: Shade some regions of cells to form a single connected unshaded path that may branch and dead end but cannot ever form a closed loop. No 2x2 can be entirely shaded (or unshaded). Symbols are always unshaded, and the path from S to G must contain all circles and no triangles.
• Variant: Every unshaded cell must have a path to at least one triangle that goes through no other symbols.
• For clarity, S and G are symbols, and a triangle cell itself is considered as satisfying the variant rule by default.
Solution code tip for Penpa+: You can highlight all of the cells of each type in "Sudoku" or "Number" mode, type U or S accordingly, then highlight the whole row and copy using Ctrl+C
Solution code: Row 13, using U for unshaded cells and S for shaded cells
