This is a vertical scroll shooting game. You can operate the fighter MissileDancer which implements lock-on missiles.
The cursor for lock-on is displayed above your plane. While pushing the shot, the cursor zooms in. You can lock-on by matching the cursor with enemies. The range of cursor and the number of lock-on increases by taking the power-up item.
