BOSSA BURGERBOSSA BURGER

Bossa Burger is a burger-building roguelite where every ingredient plays a part in the song.
Drop a bun and the bass comes in. Add a patty for guitar comping, cheese for vibraphone, and every veggie and sauce sings the next note of the theme melody. Land it on the beat and a ♪ pops!

• 4 buns = 4 chords: Classic F, Sesame C, Butter Dm, Brioche Gm7. The menu board is a chord progression
  
• Serve a burger and it rings out top to bottom as an arpeggio, landing on the bass
  
• Forget an ingredient and you hear a sour note. Add the wrong one and it clashes. You can hear your mistakes
  
• Order bells, crinkling foil, even the coins are tuned to the current chord
  

Drag the heel onto the crown, pull the foil up and around, tuck in both sides, then slide it right and down the chute it goes!
Thin foil really folds around the shape of your burger, and the finale stacks up price × multiplier line by line.

• Stars, combo, memory bonus, customer favorites and crew badges all feed the multiplier
  
• Right ingredients in the right order: ★★★
  

Each shift lasts two minutes (11:00 to 14:00). As noon gets closer, the lunch rush floods in.

• 8 customers line up at the counter, each with a favorite ingredient. Add one extra for a bonus
  
• Regulars, hurried customers, picky customers and VIPs, plus special requests like "no pickles" or "extra cheese"
  
• Toast buns, pre-cook patties in the UHC cabinet (don't let them go stale), and hold-and-release to grab just the right amount of lettuce or chili sauce
  
• Rush orders get +0.5 multiplier. Chain good burgers for a combo
  

The better you know your recipes, the stronger you get. Peek at the recipe card (R) mid-order and that burger loses its memory bonus!

• 16 days over 4 weeks. Hit the daily sales target or the shop closes
  
• Day 4 of every week is an HQ Inspection: Book Confiscated, Flickering Monitor, New Menu Test, Picky Day, Secret Critic, Hurry-Hurry Day
  
• Daily events: Lunch Rush, Old Toaster, Health Check, Group Order, Happy Hour
  
• After each day pick one reward: 21 crew badges, 5 equipment upgrade lines, coupons or recipe research, plus a new menu every two days
  
• 16 burger recipes, and your kitchen grows as your menu does
  
• Make a menu ★3 without peeking and its mastery rises for good, raising its price
  
• Recipe Book and Practice Kitchen to learn at your own pace, 3 starting shops, 3 difficulty levels
  

One run = 4 weeks = 4 genres. The recipes and chord progression stay the same; only the arrangement changes, like a remix.

• Week 1 Bossa Nova, 92 BPM: nylon guitar, upright bass, flute
  
• Week 2 Samba, 104 BPM: surdo, tamborim, cavaquinho, marimba
  
• Week 3 Disco · French House, 122 BPM: four-on-the-floor kick, octave bass, strings
  
• Week 4 Breakbeat · Drum & Bass, 172 BPM: two-step breaks, reese bass, bells
  

The same patty plays guitar in bossa nova, cavaquinho in samba and strings in disco. Even the customers at the counter bob to the beat.
