Zero Control
A 7-day Brackeys Game Jam shooter where movement is player-controlled but the turret is intentionally out of control.
Overview
Zero Control was my first game jam project. I built it with three friends for Brackeys Game Jam 2025.1, from February 16 to February 23.
Out of 2,162 entries, we finished at rank #342 overall.
The jam theme was “Nothing can go wrong” and we interpreted that as a ship system failure: the turret rotates and fires continuously, while the player can only control movement and positioning.
Core Loop
The game has 10 short survival levels. In each level, the goal is to stay alive for 60 seconds while using movement to line up automatic shots.
Destroyed enemies drop mechanical parts, which become currency for upgrades between levels. The loop is simple: survive, collect what you can, then improve health, speed, and cannon stats before the next stage.
Key Systems and Decisions
The biggest design decision was movement. Instead of standard top-down controls, players rotate engines with directional input and hold thrust to move. The ship felt different from most jam shooters, but that also made the learning curve steeper than we expected.
Enemy AI was another major challenge under jam time limits. Unity NavMesh did not fit well with 2D projects, so we switched to the free version of A* Pathfinding Project. Once it was working, we had reliable enemy movement and could spend more time on behavior design.
The most successful behavior was a blue enemy that orbits the player before taking shots. We built it by attaching an invisible tail target behind the player and making the enemy follow that target for circling movement.
Narrative Beats and Progression
Every two levels, the game pauses for a short visual-novel-style story scene. These sections gave players a break from combat and helped the full run breathe a little.
Upgrade Shop
Between levels, players spend collected parts in a shop to tune survivability and damage output.

Outcome and Lessons
We finished the project on time, but the process exposed clear gaps in architecture and documentation. The codebase became tightly coupled and hard to maintain, especially around cross-script references and persistence.
The most important lesson was scope discipline. For a one-week jam, unique mechanics are valuable, but players need to understand them quickly. Zero Control was a strong first result for us, and it gave us a clear baseline for building cleaner systems in later projects.
