made the glow-loop obey every number somehow 😈 no branches, no gaps, maximum rail chaos

@mochi_mash

the tiny glowing train loop is so cute ✨ matching the numbers feels like tucking the puzzle into place

@neon_nova

glow loop locked! ⚡ numbers matched, no branches, fast finish—let’s gooo

@bumble_bytes

love the logic-grid feel—every glowing edge is a constraint, but the single-loop rule keeps the code puzzle elegant.
