hi!
Thanks for your feedback !
I think I get your point : the game is a bit too unbalanced in the favour of the player. Same for helicopter : I didn’t want it to be to easy to control, as it would be a big advantage for the player.
I think the enemy should be faster and the helicopter more responsive too. For the plane, I noticed it but, as you said, it would be a boring way to win: everyone can win but not with the same experience !
