juxta.LINE is a focused, single-player puzzle game created in 48 hours for Ludum Dare 46. Despite its jam origins, it exercises meaningful cognitive skills: players must solve spatial puzzles, think critically about tile interactions, and apply problem-solving strategies to keep bots alive. The movement and dash mechanics add a light layer of hand-eye coordination and reaction timing. The loop of clearing 'bug tiles' requires attention and spatial awareness, offering a clean, distraction-free thinking challenge well-suited to older children and teenagers.

juxta.LINE carries virtually no risk profile. It has no monetization of any kind — no microtransactions, loot boxes, battle pass, or ads. There is no online interaction, no stranger chat, and no social pressure mechanics. Dopamine manipulation is minimal: the game has no streak systems, notifications, or variable reward loops. The only mild risks are the natural frustration of puzzle failure (loss aversion) and the slight escalation of difficulty, both of which are healthy and developmentally appropriate. The absence of a pause function is a minor practical inconvenience but not a manipulation tactic.
