Like the color of the block, the control seems fine for me. Just due to my whole weekend sprint coding on my own game... brain is pretty dead now...
Just curious... is this like a variation of 3D Tetris? It operates like one and looks like one... LOL but I couldn't find rules anywhere so you may want to type out a quick description in your game description page.
Anyway, if you have a chance, once you have done your game, please take a look of mine. It is my first game jam game so I can see a lot of things I should improve. Maybe you can see something I haven't (which would be great as the more opinions i get the better). Thanks!
Here is my game: https://kirkovski.itch.io/muz-connect
