feat: make playground more randomly

[theEvilReaper]

Proposed changes

The current playing area handling is static. This means that the ground blocks are the same in every round, allowing players to learn the positions of specific blocks. While this is not a major issue in general, players could gain an advantage over others. To avoid this, this pull request randomizes the ground. Each block is determined using a mathematical formula, and a tick loop moves the blocks around during the game.
