PlanetCore

🌍 PlanetCore – Drill Deep. Evolve Fast. Survive the Unknown.

Descend into the heart of a living planet in this intense 2D drilling survival game. PlanetCore fuses high-stakes exploration with brutal terrain, stunning biomes, and evolving dangers.
You control a fully upgradeable drill machine, carving through layers of rock, magma, and ancient mystery in search of rare ores, powerful relics, and the truth hidden at the core.

But depth alone won't be enough, you'll need your wits. Navigate labyrinths of unbreakable stone, solve puzzles to access hidden gem caches, and complete dangerous missions to extract rare materials. Compete or clash with rival drillers, endure quakes, eruptions, and devastating chain reactions deep below. As you dig closer to the core, uncover a world-ending threat, and become the only hope to stop it.

Just made this retro track for fun but later I will use a more sophisticated software for my game.

Is this inspired by Motherload? https://www.crazygames.com/game/motherload

[normal crag]

Heavily yes! I Want to make something like this but way better 😄

[short finch]

nice 👍

hopefully i can check it out

[normal crag]

Emerald!

"they're minerals"

[bold marten]

Cool looking game

[normal crag]

I have made it possible for infinite depth world

[normal crag]

Doing a speed limit test to see how performance is. We won't be able to drill this fast in the release of course haha!

With this performance test, it confirm the game can run on mobile.

Graphic settings is a bit lower for this test.

compact gems:

and now less square looking:

[normal crag]

Working on the lava!

[dusky tinsel]

This looks sick! Keep up the good work!

[normal crag]

I love how it flows.

hi supreme, i am working on an AR app and i think i can figure out a way to sort of promote your game. probably i would need a short snippet like this ..a few seconds worth of it. let me know if you can talk

[normal crag]

I am interested. I am still very early stage in my project. Once I'm done with my lava simulation, I can make a snippet showing lava + different terrain and gems while player is drilling.

[civic otter]

super! this is good work. i am designing a social platform think of lens but without the discovery issue. we could have ar scenes of some of your work within the AR context (swipe, tap etc) and you getting full credits.. if this goes on i honestly see a new shift

[normal crag]

Now working on lava procedural generation

[dusky tinsel]

Great stuff!

[normal crag]

Added metaball effect on the lava

[normal crag]

Next step would be to store lava particle to disk when outside of view, avoid tile to spawn new particle when already spawned and also predict particle trajectory for particles that got despawned and were currently falling.

[normal crag]

increased performance dramatically. When player was drilling, fps droped to 80. Right now its around 380 when drilling and 450 when standing still. With a massive performance shift, I am now confident in adding heavy stuff to my game.

5. Thruster Output – Max engine movement speed
6. Inertia Brakes – Braking force for movement
7. Thrust Vector Accelerators – Acceleration rate
8. Afterburner Ceiling – Max rocket speed
9. Afterburner Rampers – Rocket acceleration rate

Custom Control Modules
10. Variable Bore Governor – Control max drilling speed manually
11. Throttle Governor – Control max movement speed manually
12. Accel Governor – Control acceleration rate manually
13. Ignition Governor – Control drilling start speed manually

Efficiency & Durability
14. Quantum Efficiency Matrix – Energy/fuel consumption reduction
15. Drillhead Alloys – Drill bit material upgrades (Iron → Steel → Carbide → Adamantite, etc.)
16. Spindle RPM Modulator – Drill spin speed
17. Hull Plating – Engine armor
18. Thermal Shroud – Reduces heat emitted from engine
19. GeoThermal Shielding – Resistance to terrain/lava heat
20. Blast Baffles – Explosion resistance

If you have any other ideas for engine upgrade, feel free to share.

If you drill too fast on fragile ores, you break them or make them less valuable 😄

[normal crag]

testing insane amount of lava haha!

[normal crag]

Here is my new UI working perfectly 😄

[normal crag]

Smooth terrain deformation!

[uncut spindle]

Add underground vulcanos like in Oxygen not Included maybe

[normal crag]

im doing a shift with the game, instead of squared tiles I won't use any tile at all! Everything will become ... dynamic. Any shape possible. A complete planet where you can circle around it and shape the terrain in any way you want as if you are drawing something on paint with a brush tool. thats how new drilling mechanic will work.

[uncut spindle]

Dang, that's gonna be hard to implement, isn't it?
But I love the idea, excited for the demo/ full game

[normal crag]

Here is the new concept, showing all layers in a short world. No ores or lava for the moment. Full circular planet. Smooth drill.

[normal crag]

the new ore system looks nice

[normal crag]

this is what happen at the very core of the planet !

[uncut spindle]

Dang, looks funny. I like it

[normal crag]

this is what the planet looks like when super tiny size (no lava yet, currently adding it) in the real game this will be enormous, around 1000 times bigger? Next goal is adding the lower mantle and the core filled with lava + innercore, a bright yellow texture.

[normal crag]

Added lava + engine heating + smooth slide interaction on terrain + physic force interaction between lava particle and player

[normal crag]

Currently adding plate tectonics of the planet + mountains!

[normal crag]

showing off my lava

[cyan wing]

Been following your progress for a while now, and I wasn’t sure if you had already planned this but maybe the lava should slow the player significantly, since it is molten rock after all

Would make it seem less like a background decoration and more like a real, physical force in the world

[cyan wing]

By “slow” I specifically mean I think the player should barely sink at all in it, like real lava

As long as that doesn’t contradict your vision!! If you have a plan for it go with that ofc

[normal crag]

Yes that is in my vision!! Also I will make the player need to use rocket force to be able to swim faster inside lava in the core! 😄

[normal crag]

Magma + Lava Smooth blend!

[normal crag]

currently drilling to the mantle layer! Soon I will include lower mantle, outer core and inner core!

[normal crag]

Lower mantle layer

[normal crag]

ITS GETTING HOTT!!

[normal crag]

I know it looks kind of wierd from a tiny planet perspective and from far away but here it is, I added the outer core and inner core layer on my PlanetCore game!

Next goal is adding the actual game mechanic! There will be upgrades, missions, story and will add many hazard in the planet such as gas explosion, earthquake, terrain pressure effect that make the rocks close on itself when you drill them, etc... 😄

[normal crag]

And now working on emissive for lava crack

[normal crag]

Added fog effect!

[normal crag]

Death explosion! 😄
