That’s a sweet combo, I love it! Start with a solid base of core stealth rules—cover, noise, sight lines, and a clear objective. Then layer on extra options: timed gadgets, environmental triggers, or alternate routes that let players pick their own risk. The trick is to keep the rhythm tight: drop a quick chase or a surprise alarm every 30–45 seconds to keep the heart racing, but let the player plan in the moments before. Think of it like a game of chess that also feels like a high‑speed chase—strategic moves that still feel urgent. Keep tweaking the pacing with small “wow” moments, and you’ll have a level that feels both precise and thrilling!

You nailed it! Clear rules lay the groundwork, then splash in gadgets and secret paths for that tactical flair. Keep those quick alarms to fire up the adrenaline, but give a few seconds of calm for the player to plot their next move. That mix of precision and pulse‑raising pacing is the sweet spot for a killer stealth level. Keep iterating, and you’ll end up with something that feels tight, exciting, and totally immersive!
