Cardboard Delivery Service

I strongly recommend playing the Windows build for better experience

About Cardboard Delivery Service

You work in a Cardboard Delivery Service. And no, you don't deliver cardboard, your job is far more important — you deliver handshake packets between towers of your area network.

The towers can emit and receive signals, but they cannot establish connections on their own. That’s where you come in.

Be careful: the signal cannot pass through objects. While this is not a problem for large network towers, it becomes a serious challenge for your small van and hub towers. Keep an eye on your signal indicator — if you drive too fast or too far, you might lose connection entirely.

Gameplay

- The goal of the game is to connect signals between the large towers and build a working network.

- Large towers are marked on your screen, making them easier to locate.

- Each tower can act as an Emitter and/or a Receiver.

A tower becomes an Emitter once it receives a signal from another tower. Once you turn all receiver towers into emitter towers - you win. (Icons will guide you what's left to connect)

- To successfully connect distant towers, you should use hub towers (the smaller ones). They help you route the signal around obstacles and carry it from one large tower to another. Hub towers also have smaller markers on the screen.

- If an obstacle appears between the signal source and your van, the connection is lost. That’s why hub towers are essential for maintaining the signal.

- Once you connect a signal to a large tower, the hub towers used in that connection become available again, and the signal is then transmitted directly between the large towers.

- Monitor your signal strength. If you move too fast, you may lose your connection.

Post-Jam Changelog

(v1.0.1)
* Fixed an issue where hub tower marker UI was not being properly destroyed.
* Fixed overlapping UI

(v1.0.2)
* Changed web build settings to display game in web correctly

(v1.0.3)
* Radio Wave Particles: Resolved an issue where signal particles would pause at long distances by setting the Particle System culling to "Always Simulate."

* World Bounds: Removed an invisible wall to allow for southward driving.

* Signal Softlock: Fixed a potential softlock by adding an additional Hub Tower, because one specific tower was unable to relay signals if selected as the source by random.

* UI Cleanup: Fixed a bug where UI markers persisted after abandoning a shift, ensuring tower widgets are properly cleared for subsequent sessions.

* Connection Logic: Patched an exploit that allowed players to create cyclic connection chains through Hub Towers, enforcing intended network constraints.

* Collision: Fixed bad collision on the ramps

Developer Note

* Assets: All assets were created by me, except for the soundtrack. I did not opt out of the Audio category because I created all of the sound effects (derivative work). Please take this into account when rating the Audio category. If you feel it’s not fair, you are free to rate it with 1 star.
* Use of AI: The only place AI art was used is the cover image (the logo uses the same image), and even that is a derivative work based on AI, but not entirely generated by it.
* There are known issues with UI that will be fixed soon. I really need to sleep
