I removed messages which have been displayed before entering the stage first time because it was pointless. The rest of the content remains unchanged.

I have added a visual effect that touching a green panel at the1st stage or a green column at the 4th stage is reacted by color (in order to clearly indicate the touch). And the app name has been changed to 'jet ball cosmic tour' (namely, from 'traveler' to 'tour').. According to the change, I have modified some labels and descriptions in the game. Additionally some settings have been readjusted. Basic contents haven't been changed.

I have added a setting randomly displaying some notes about the game right after the start. Additionally, I have adjusted the appearance probability of obstacles (aliens) on the first station. As the early course has been easier a bit, please have a try to go around more stations!

I have changed how to indicate a “RESTART” button from double-tapping to long-press somewhere on the screen (about 3 seconds). The button appears when your finger is lifted. Additionally, I have modified some visual effects and changed the App's Icon. Basic game contents haven't changed.

I have adjusted the force of jets direction of which is to the top on the board to push the ball harder. Additionally, I have re-arranged some gimmicks according to the rounds. Basic contents of the game haven't been changed.

The app has been adapted to the display of recent devices in 2021 including iPad mini. The game contents haven't been changed.

I have added an indication of score on the screen. It increases or decreases following the conditions. The ball's touching the green panel, robot guard and green column is each +100,  passing through the station is +10000 and touching the rockfall at the 5th station is -20000. (The status as the cosmic traveler is rated by the count of of passed stations as before. The count is displayed by double tapping.) Additionally, I have set some gimmicks from the third round. Please have a try!
