Glad you liked the game and yes was going for a sort of mobile game style.
No I’ve not used any of the gdtv courses (tbh never heard of them until this game jam need to check it out)
The planets and ship is low poly but it’s a mix of a little voxel/pixel art I don’t think you can tell the pixel/voxel art since I made it a solid colour for the land or the water or lava.
But I used blockbench.net really simple and easy modelling. look at like a simple tutorial maybe use the car tutorial from the official blockbench YouTube channel. And then I used ChatGPT to show me a low poly small world for inspiration and using that picture I tried recreating it my way and it turned out great.
And for the UI I just used my pixel art (that idk I just had experience from stuff and looked at inspiration from other games or images I found online)
Key point use inspiration ig
