ORBIT BREAK

About
Orbit Break is a space breakout game with roguelite elements, blending vector graphics and SFX inspired by the AdLib era. Navigate an uncharted sector of space, completing six missions in any order that you choose, with missions ranging from clearing asteroid fields to destroying alien anomalies and orbital structures. Collect minerals, upgrade your ship, and push deeper into hostile territory. 

Note: This game contains flashing visual effects.

Tactical Briefing
This section offers guidance for players finding the demo challenging. It contains light spoilers. Skip ahead if you prefer to discover the missions and gameplay on your own.
 
Supply Station
The player can travel to any mission, but the demo is designed for returning to the Supply Station between missions. Prioritise weapon upgrades, restock missiles, and repair hull damage before heading out again. 

Ball Creation
You can create as many balls as you like per mission, so use this to your advantage. When purchasing the cargo bay upgrade, two balls are created at once, so remember to launch twice. The extra ball is also available at the start of each mission. 

Weapon Systems
The laser and missiles can be fired simultaneously for maximum firepower. But remember that the ball is also dealing damage while you fire.
All three systems work together. 

Recommended Routes
Twin Delta - A good starting mission. Take your time and focus on collecting as many minerals as possible as this is one of the most rewarding early missions. 

Mining Rift C -Best attempted once you have missile pods. The asteroids here have low HP and two well placed missiles can clear one quickly. 

Zero Sector - Not too difficult, but attempting this after the other easy missions means you'll have decent firepower for easy credits. 

The Derelict - Requires precision timing. The outer structures have high HP while the core is weaker, so time your shots to hit the core. The laser is useful here, but try not to neglect the ball. Once the core is destroyed, structures will still need to clear the screen, so stay alert. If you need extra credits, focus on the outer structures as they drop a high number of minerals. 

Crystal Anomaly - The crystal fluctuates between vulnerable and invulnerable states. Time your shots and bring heavy firepower to make quick work of it. Note that you're unlikely to gain minerals from this mission, though it has a higher credit payout. 

Orbital Array - The toughest mission, requiring heavy firepower. Focus on the satellite arms as once all arms are destroyed, it explodes. Be warned, the more you destroy, the faster all remaining satellites move.

Alternative Routes
The medium missions can be completed early, but they are designed with the expectation that the player has at least unlocked the laser. 

Technical 
Built with vanilla JavaScript and HTML5 Canvas. No frameworks, libraries, or external dependencies. All graphics are rendered in real time using vector drawing. Audio is generated at runtime using the Web Audio API. The game runs on a fixed 60 TPS tick based simulation with frame interpolation for smooth rendering on any refresh rate. 

Personal Note
Orbit break started as a rough sketch exploring how to expand on the classic breakout formula. The scope grew quickly, so I cut it down into a compact demo that showcases each system in the game. Players might find the first few missions challenging, but progression is intentionally generous, as there are only six missions, I wanted every upgrade to be available by the final mission. 

The demo is complete as it stands, but I am open to creating an expanded version later on if there is enough interest.
