Jeferson Silva - Wishlist NULLPTR on Steam

I wrote a breakdown on how I used small visual effects to make the puzzle grid in NULLPTR feel alive.

Meet Yosai's sentinels: Oni patrols red routes, Yagura watches sensitive data, Tengu displaces nodes with its winds, Yumi restricts routes with perfect aim, and Katana will cut through your connection.

Wishlist NULLPTR on Steam!

What if the hacking minigame was the whole game?

In NULLPTR, hacking is a puzzle of timing, logic, and creativity.

Wishlist now and become a ghost in the system.

#PitchYaGame #IndieGame

Not all hacking games are about coding. NULLPTR is a real-time tactical puzzle where stealth, timing, and creativity turn threats into opportunities. Launching Nov 25, 2025, wishlist on Steam!

Another synergy in action: stepping out of the central STAR sentinel floods your stack with yellow data, expanding the orbit radius of every SAT sentinel in the server.

In NULLPTR, sentinel behaviors combine, creating synergies that turn small threats into big ones.

Getting comfortable with hacking? The Mutator shows up to turn the grid into a living challenge. Firewalls, gates, data nodes and even databases will change colors when they meet this sentinel.

#indiegames #gamedev #indiedev #puzzlegame #gaming

You can only cross a bridge node if the data at the top of your stack memory matches its color. Moving backwards and erasing all traces over a bridge automatically forces that data back to memory.

What if the hacking minigame was the entire game?

#screenshotsaturday #indiegames #indiedev

Tunnels let you jump horizontally or vertically to any node of the same color, allowing you to move faster and access areas of the server that were previously inaccessible.

#indiegames #indiedev #gamedev

Firewalls (diamond-shaped) block download attempts if your route passes through them and prevent passage if your memory contains a node of the same color. This often forces you to find alternative paths, sometimes leaving you exposed to sentinels.

#indiegames #gaming #puzzlegame

You can use the stack memory to store colored square nodes and write them into empty square nodes. As the name suggests, the memory works as a stack, so the last node you add will be the first one to come out when you need to rewrite a node.

#indiegame #gamedev #puzzlegame

Thanks! The Atari was my first videogame and I have good memories of playing it with my parents and brothers so it is definitely an inspiration for me!

A gate with a number in it will only open if you choose a route that contains exactly that amount of matching color nodes. The route profile helps you keep track of nodes in your current route.

#indiegame #gamedev #puzzlegame

Achieve a ghost run by hacking a server without being detected. Every server in the game can be hacked this way if you learn how to exploit the flaws in each defense system’s behavior.

#gamedev #indiegame #puzzle

As you move while connected, you leave behind traces that can be detected by some defense programs. Installing backdoors may enable different attack routes less exposed to detection. You can also erase your traces by moving backwards along your path.

#gamedev #puzzlegame #indiedev

Every run begins by selecting a server to hack. Once connected, your objective is to download data from all databases and then disconnect without being detected. After your first move inside a server, you have 20 secs before you are traced and eliminated.

#indiegame #indiedev #gamedev

Every defense has a flaw. On November 25, 2025, you'll have the chance to prove it.

Yep! It's nice to think it will finally be done, though I’d be lying if I said it isn’t also a little scary. 😅

CARTA ABERTA À GAMESCOM LATAM: drive.google.com/file/d/1p86T...

Hi english speaking games industry people, this is an open letter from a group of brazilian game devs to the organization of Gamescom Latam, complaining about the bad conditions and mistreatment of developers by the event. There's an english version here: drive.google.com/file/d/1YUmh...

This is NULLPTR—a different kind of hacking game where you’ll need to explore system rules and turn threats into opportunities to uncover safe routes to the databases. Demo available now on Steam, full release planned for 2025:

Hacking, reimagined

This is the game I've been working on called NULLPTR (null pointer), a hacking puzzle game where your goal is to manipulate levels and exploit enemies' behaviour in order to create safe routes to databases.

There is a demo on Steam and I'd love to get some feedback!
