Hnos. Escúper Tonio (Scooper Tony Bros.)
Soy yo, Tonio!
Tonio is your guy. He's always there when you need a hand, or a pan dulce. He looks familiar because he's family. He wears your colors. He likes hip hop. He's responsive. He runs, he jumps, he bumps, he stomps, he digs, he drills, he activates switches and pulls levers. He's Tonio!
What to Expect in This Demo
A tight 8-screen loop showcasing a new platform-puzzler engine built from the ground up for original '80s NES hardware using bare 6502 assembly, featuring a responsive environment, complex enemy interaction, and light puzzle elements.
The in-browser experience on this page includes the following enhancements:
- 🏆 Achievements: A custom achievements system embedded directly in the web player (emulator) tracks 20+ achievements in real time as you uncover secret mechanics and environmental interactions that showcase the engine and might otherwise go unnoticed.*
Can you unlock all the achievements?
- 📺 Shaders: Toggle real-time CRT shaders and switch between crisp integer scaling and smooth vectors at various zoom levels.
- 🎮 Controller & Keyboard Remapping: Plug in your favorite gamepad and remap the buttons or customize your keyboard layout.
- 💾 Save States: In-browser save and load so you can practice tricky jumps and mechanic interactions.
*Note: In-browser achievements are featured in the web player only. The downloadable .nes ROM runs on authentic NES hardware, flash carts (EverDrive, PowerPak), or emulators (Mesen, FCEUX, Nestopia, Nintendulator, etc).
The Game
An authentic NES 8-bit platformer built from the ground up.
The Characters:
Múfintop (Muffintop)
There's currently only one enemy. He's a muffin.

He's not a fun guy. He's your enemy. Even though he's soft around the edges, he'll still knock you out if you rub him the wrong way. If you're lucky, you'll get in one more shot on the way down. All gluten, no highfalutin.
Stomp 'em, flip 'em, puff 'em, bump 'em, chop 'em, drill 'em, flip 'em back over. He's game (and he's also critical for some of the puzzles).
Dice: "¡No soy hongo, soy múfin!"
He says: "I'ma muffin, not a mushroom!"

Flaits (Flights)
In addition to Múfintop, there exists small white birds affectionately known as Flaits (Flights). They jump around minding their own business until they get spooked when you get too close. They're central to a few of the Achievements.
Puerquito Espín (Porky Pine)
Another enemigo hecho de pan dulce that currently only exists in Tonio's pesadillas (nightmares). He's believed to be made of piloncillo (brown sugar), canela (cinnamon), and nothing nice. A dark brown cookie with spines and the ability to roll into a ball! ¡Trucha! Watch out, here he comes!
Gameplay & Distinctive Mechanics
- Dynamic Tool Abilities (Shovel & Drill): Beyond standard jumping, tools fundamentally change movement, environmental interaction, and combat. The shovel allows direct downward digging through dirt blocks, while the drill turns the mid-air power dive into an aggressive downward bore that shatters enemies and blocks, separating them into flying tiles. Tools are time limited.
- Dive Puff: Standard dives produce horizontal "puff" shockwaves on ground impact that knockback nearby enemies and help them clear obstacles. Performing tool-assisted dives with the drill or shovel skip the dive puff entirely, leaving Tonio vulnerable to flank attacks upon landing.
- Topple Flip: Flip an enemy with an upward block bump and then flip them back to their feet the same way, as many times as you can manage.
- Skid Bump Knockback: Rather than taking damage during an evasive maneuver, colliding with an enemy while actively skidding turns your shoulder into an offensive attack, launching the enemy away with custom knockback physics.
- Revenge Stomp (Resuscitation): Dying isn't an immediate game over. If you're in a mid-death leap and manage to land on an enemy on the way down, you trigger a "Revenge Stomp" that resuscitates Tonio and resumes play from the landing point!
