-Rule- Place the falling blocks in the 16x16 field by operating the buttons or flicks. When the blocks are aligned next to each other, the line disappears and all the blocks above it go down. The game is over when blocks are placed at a height of 16 or higher. -Mission mode- Select a stage. You can clear the stage by erasing all the blocks (dot pictures) placed from the beginning. The time limit is 10 minutes. It will be evaluated by the time you clear the stage. -Arcade mode- Blocks will appear from the bottom of the field at regular intervals. There is no time limit, but as time goes by, the time interval between blocks appearing becomes shorter. -Use / reference material- Dotown https://dotown.maeda-design-room.net/ Pipoya https://pipoya.net/sozai/ PeriTune https://peritune.com/ Maoudamashii https://maou.audio/ Pocket sound https://pocket-se.info/
