You're an intern at the Mars Rover Control Center, and your first mission just went live. There's one problem: signals take time to travel 225 million kilometers.

Build command sequences, send them into the void, and watch as your rover executes them with frustrating delay. Scan uncharted sectors, gather valuable crystals, and navigate treacherous terrain — but remember: you won't see what's happening until 2 transmissions later.

Can you complete the mission before your rover's systems fail?

🔹 Available Commands:
↑ ↓ ← → — Move across the grid.
Scan — Reveals fog of war in a 3×3 cell radius.
Gather — Collects crystals from your current position.
Repair — Restores damaged rover subsystems (consumes resources).

🔹 Signal Delay:
Visual feedback occurs every 2 transmissions. Between updates, the rover executes your queued commands blindly — you only see text-based status reports.

🔹 Martians:
Local creatures move randomly after each of your turns. If you end up on an adjacent cell or the same tile — they attack and damage your subsystems.

🔹 Terrain Hazards:
Cliffs and craters deal damage when entered. Craters can be crossed, but require a double command and increase the risk of wheel/engine failure.

🔹 Damage & System Failures:
Each malfunction degrades rover performance. Damaged systems may cause the rover to skip movement commands or shuffle the order of queued commands. If 2 or more critical subsystems fail (Camera, Antenna, Wheels, Engine) — communication is lost permanently. Game Over.

Your goal is to collect all crystals in the Mars sector.

I've been wanting to experience the space program for a long time!

nice music! hard to understand how to operate. missing keyboard controls. ui is too small, pls add full-screen mode

Good concept, can't say much about gameplay - I didn't understood it.

Overall, I think the idea is really cool. It feels like there’s room for thoughtful play and some creative problem-solving, rather than just being a simple “pick the right option” kind of puzzle.

I especially like the mechanic where not all commands go through — it adds an interesting layer where you have to remember which inputs failed, especially as you progress. Keeping track of which signals were sent and which weren’t becomes really important, and that’s a nice twist.

It wasn’t immediately clear how everything worked at first, but once it clicked, it started to make sense.

One thing I’m still a bit unsure about is what exactly you can and can’t step on. At first I thought the squares were meant to be interacted with directly (like digging or activating them), but it seems that’s not quite the case. It feels more like you’re navigating around the edges and searching, but then it’s a bit unclear what the purpose of some other buttons is. I get the idea with the chest acting as an obstacle, but beyond that I’m not entirely sure how everything ties together.

Still, overall it’s a really interesting concept — nice work!

Cool idea, I like the idea of qeueing the movements. The graphics and audio also fit well. I think the main lacking element would be more intuitive puzzles. Maybe you could send signal to different recievers to do something etc. Nice job on the entry!

Great idea, board game vibe, and an interesting puzzle! Good luck with the game!

The little green men are very funny. It's a great idea, but the predictability of the Martians' behavior wasn't enough.

It's a very cool idea, and I had a lot of fun playing it. We all know that reading the "introduction" isn't always a priority, so I immediately jumped into the gameplay, which is incredibly intuitive.
The only thing I would like to have is the ability to move the camera slightly upward, zoom in a bit, and so on. However, this is not part of the gameplay, so I don't think it's worth mentioning.

Really clever concept! The music is great. One small suggestion: please add an in-game rulebook. Wishing you the best of luck with the project!

I enjoyed the idea of the game with the queueing and all that. There are a couple short comings with various bugs and the ui but its good what you've achieved in 3 days. Good job :)

A fun, simple game that's addictive. The rover-kill mechanic is well-implemented, lol. The music is well-chosen and fits the game perfectly.
I like that not all commands can be executed—it's a bit random. It's addictive!
I'm on my fourth playthrough, and I still can't get all 5 crystals—it's a challenge!

The project looks very interesting. It’s clear that the mechanics were carefully thought through. However, this genre isn’t really my thing, so I can’t evaluate it objectively.

Thanks for the tutorials both in the game and on the page. I still had to figure things out through trial and error to understand how it works in practice, but it’s convenient that you can always go back to the description if needed.

As I understand it, there’s no way to attack the martians — you can only avoid them. I’m missing an attack option)

Love this clever puzzle design! The unreliable signal and delayed command mechanics are such a fun twist, bringing great strategic depth and replay value. The style and sound fit perfectly, though a few rules feel a little unclear at first. Overall such a creative and well-thought-out game!

that delayed signal thing is lowkey genius makes it so much harder lol

That Martian is a menace. This was a lot of fun. I liked the delayed commands and the mixed up signals were an interesting addition. Everything was straight forward and worked well. Good stuff :8ball:
