@73N: KEEP. HIM. ALIVE. is a compact factory-building puzzle game that delivers surprisingly rich cognitive benefits for its jam-game scope. Problem-solving is the undisputed core mechanic — players must analyze resource flows, design assembly lines, and iteratively debug their factories to produce increasingly complex parts for their steam-powered robot friend. Spatial reasoning is heavily exercised as players mentally map belt routing, component placement, and throughput bottlenecks on a 2D grid. Strategic thinking and learning transfer shine as solutions to early puzzles become building blocks for later, more elaborate ones — a hallmark of well-designed systems games. Math intuition develops organically through managing production ratios and timing. The light narrative framing (saving a beloved robot companion) adds a modest but genuine layer of empathy and emotional investment, giving purpose to the mechanical puzzle-solving.

| R3 | Social risk | 0.00 | |
Risk exposure for this game is exceptionally low. It carries no monetization whatsoever — no ads, microtransactions, loot boxes, or subscriptions — making it one of the cleanest profiles possible. Dopamine manipulation is nearly absent; there are no streaks, variable reward schedules, FOMO events, or push notifications. The only mild risk is escalating commitment: the factory-building genre naturally encourages players to sink more time into optimizing and expanding, which can make sessions run longer than intended. The 'keep him alive' framing creates a slight sense of stakes (loss aversion) but is not punishing. Content is entirely benign with no violence, mature themes, or stranger interaction. This is a remarkably safe game.
