Though the rule is super easy, it is the game that correct scroll operation needs.
You let a screen scroll and move a central object not to come in contact with a wall and an obstacle and move it to the checkpoint.
Ranking is decided by the shortness of time to the checkpoint.
To an obstacle, there are things shooting an article turning around, a moving thing, bullet and disturbs movement.
6 rounds in all.
In the round that you cleared, choice is enabled.
The size of the movement object changes in Easy-Normal-Hard, and a degree of difficulty changes.
If a web access is in a possible state, you can watch world ranking.
Possibly you may be in the third place.
Thank you!
