Dear customers.
We updated the game to Version 1.20
Please check the following points.

We raised the mobility of F-104.
We lowered the mobility of F15Ace and YF22Ace.
Added the display of "ENEMY LEFT".
Added STEAM-Achievement of the Extra stage.
Tripled the distance that player can see.

It is not a bug if the last your enemy start to escape the combat area.
We confirmed by test play that all levels can be completed.
"LEVEL 3 with ACE mark on STEAM-Achievement" is really difficult.
Flight Shooter Game beginners can play other stages instantly.

Thank you!
