well....it isnt bad...but could be better...you should set a briefin and an objective in the missions because...dude =$ it a little tooo repetitive....adding new objectives like : drop these soldiers on the marked place,protect the cargo plane,survive a number of waves....some missions like these should make it a little minus repetitive(srry if i write it bad i am not engish).
Its a good start but need some fixes...dont be angry...i am only tryng to help you make your game better
ITS A FUN GAME BUT AFTER A WHILE YOU ARE DOING THE SAME THING OVER AND OVER AND OVER AGAIN AND AGAIN.
It's okay but gets repetitive fast.
Side note, the planes in this game are World War 2 style, not World War 1 style.
This is a very fun game. I really enjoy the later levels where you really have to plan your movement. One thing that would be cool is to add some more advanced aerobatics, like if an enemy is behind you maybe you could pull a loop and arrive behind them, or do a dive when attacking the ground enemies. But I love how smooth the game is and how the plane reacts. One other little thing it does seem a bit more WWII-ish than WWI -- the planes seem somewhat advanced for WWI but it's very fun to play. Nice JOB!
