#defensegame

ok the PREMISE of this game alone got me.

Defend My Room — free browser game, no install, no account. a little brother invades your room and you click/tap him as fast as possible before he wrecks your thesis, your makeup, your spicy noodles, or your idol merch. genuinely relatable if you have (or had) a sibling.

but it's not JUST a clicker — there's weapon unlocks, a combo scoring system, an actual boss fight, and star ratings. way more built out than I expected from something this silly.

what it is

little brother runs around your room, you click him before he reaches your treasure zones (thesis/makeup/spicy noodles/idol merch). zone HP drops if he gets there. lose all HP or max your blood pressure meter = game over. 5 stages, gets faster and more chaotic each one.

stage 1 — slow, tutorial, bare hands only

stage 2 — faster, unlocks the Mallet

stage 3 — rush mode, unlocks the water sprayer

stage 4 — boss shows up, unlocks the bait

stage 5 — everything at once

HP carries over between stages with a 20% bonus, so defending all 4 zones evenly beats tunnel-visioning one.

the weapons

👊 backhand smack — default, rapid taps build combo

🔨 justice mallet (stage 2) — 2x damage, charges Mom's gauge 2x faster, best vs boss

💦 water sprayer (stage 3) — slows brothers 50%, use preemptively on fast ones

💵 king sejong bait (stage 4) — throw it, nearby brothers get distracted 6 seconds, throw it far from your zones for max effect

mom's special move

there's a rage gauge at the top that fills as you smack brothers. hit 100% and you can summon Mom, who wipes the whole room and restores 20% HP everywhere. Mallet charges it 2x faster, so Mallet + Mom combo is the strongest play when things go sideways. save it for when 2-3 brothers swarm at once.

the boss fight (yes, really)

stage 3 onward, a boss brother shows up with way more HP (5 bars) and goes straight for the cosmetics zone. Mallet is your best bet here — sprayer and bait are a waste of time against her.

combo system

chain kills within 3.5 seconds of each other to keep your combo alive. higher combo = bigger score multiplier. this is where the actual score comes from, not just raw kill count.

star ratings

⭐⭐⭐ perfect: 75%+ average zone HP

⭐⭐ good: 40%+

⭐ cleared: below 40%

clear all 5 stages and you get a shareable ending card with your final rating.

who's this for

anyone who wants a quick free casual game

people who want to jump in with zero setup

anyone with a sibling (this WILL hit different)

reaction-speed enjoyers

a satisfying way to blow off steam for five minutes

works great on mobile touch too — good subway/break game.

tips

sprayer first on fast brothers, then finish with hands or mallet

throw bait as far from your zones as possible

don't spend mom's gauge the second it fills, wait for a swarm

HP carries over so finish stages fast to bank more for the next one

play with sound on, the hit sfx genuinely add to it

anyway I don't have a little brother but I get it now.
