You can almost see it in the game. When you press Play, the message "Enter load data" will appear, so enter the load data. (Load data will come out when you press "Create" to create a stage) It's just that. (You can change the block with the w key and s key.) If you select play, enter the save data and press the Y key while playing, you will see "Restart from the start" and "Leave the course". It will come, so please choose either one. Press the z key to dash. Perhaps the bugs that pierce the wall are gone.
