An opensource in-development entity-based internal block-stacking engine. Its focus is on high performance and low amount of memory allocated per player.
This is not a complete ECS game.
It's not built on top of Johnny Turbo's LD43. Foundation of blocks_of_data is: Unity DOTS.
This project also works on Unity 2021+.
You can use this internal engine as long as you understand that you need to credit this source code's original creator, Aymir Dmitrievich Danilov aka Tetro48.
