STRATEGY & TIPS FOR BRAINROT: CASTLE SIEGE!
Keep your eyes on where you're going, not on your own character — peripheral awareness of hazards matters more than watching yourself.
Accept that an early death is often the cheapest way to learn a section — treat the first few tries as scouting, not scoring.
Survive first, score second — most arcade games hand out points for staying alive, so protect your run before chasing risky combos.
Learn the pattern and timing of obstacles or enemies — arcade games are often built on repeating cycles once you notice them.
