Hello.
I am working on a small voxel game prototype: https://kweken.itch.io/voxel-game-basics
I have seen many voxel games, almost all of them disappointed me.
Usually they focus around world generation and do not go further.
Often there is inconvenient controls or basic features are missing.
Separately worth mentioning optimization, voxel worlds for some reason try to generate the whole world in depth and because of this they cannot show the world up to the horizon, which would not be the case if they used a regular height map. However my prototype does not implement this, but for me it is an area for future experiments.
I decided to limit the world to the size of 32 by 32, while it is possible to place blocks outside of this size.
I also made portals between worlds, by the way each direction has its own color and sound.
In the future it would be fun to have a multiplayer game where each player has their own island and one can travel to neighboring ones. Just dreams.
In my current prototype there is no crafting, only 5 types of blocks.
Nevertheless there is generation of structures in 20% of worlds.
I also added glowing balls for collection, 10 pieces, after collecting all of them you hear a victory melody, but that is all, they do not play any role, except for the role of a spontaneous activity for 10 seconds.
In the game there is a small horror scenario, a hint is in the world 0 0.
For the music I made a procedural change of arrangement layers, and also manually wrote 3 short melodies, each 4 bars.
When saving, only the delta is recorded, so the save file can be small, mine weighs about 10 kb.
I will be glad to hear any opinion.
