Speed-run tip: slice debris with the pizza cutter in short drags so you do not spike the patient's pain meter.
Always cauterize with the lighter before stapling; the burn stops bleeding and you save a precious second on cleanup.
Remember to drag the vacuum in slow circles. A quick tap misses shards and costs bonus points at the end.
When the heart rate flatlines, mash the defibrillator rhythmically instead of spamming it - three taps usually revives instantly.
If you overheat the lighter, swap to the gel for a moment. The cooldown is faster than waiting for a full reset.
Look for hidden tools in each scene. The car battery upgrade in level 4 turns the next boss surgery into an easy clear.
Staples count as combo hits - chain them after vacuuming to push your star rating into gold territory.
Practice on the tutorial patient to perfect the timeline. A flawless run gives you enough bonus blood for the tougher surgeries.
