Windows, macOS and Linux builds are all released! Hopfully everyone can play my game.

======= UPDATE 2 ======

• As I realized that most people would like to learn with the in-game process, I extented the tutorial a little bit.
  I hope that makes the gameplay more understandable.
• I got feedback that it's kinda difficult to drop blocks on desired positions, as the game track mouse pointer as 'ground position', rather than the piled up blocks. So some extra codes are added to make the drop & drop easier:
  • When pointing to the lower part of a block pile, mouse position is used as 'GROUND POSITION`
  • When pointing to the upper part of a pile, drop zone is intepreted as the pile's top.
