In the Memories

Falling Cubes

A casual mobile game that was designed to make me calm down
when I am in bad mood. Cubes are falling down continuously,
You can just watch they are moving.

This was a test app to experiment Unity ECS feature.
That feature was not bad
but there was not enough documents and
missing many utility features.
It was very inconvenient to use. So I dropped to use it.
My next project, Dungeons, will use my own ECS library.
