Standing still is almost a punishment. Health keeps bleeding away, kills refill it, and the safest habit is therefore the most reckless one: rush forward, shoot cleanly, recover, and immediately chase the next target. With the full version unlocked, the complete run and later content are available from the start, while procedural rooms keep repeated attempts from turning into simple route memorisation. The only real irritation is visual clutter, since smaller enemies can vanish into the glowing background at exactly the wrong moment.
