Thanks for playing my game, and I'm glad you like the presentation and idea :)

Yes I wish I had more time to finetune the mechanics. In hindsight I should've made the terrain less damaging to the chopper and the enemy bullets + mines more damaging. Now it's too easy to get killed from just touching the terrain. 

I purposely made the control/speed (inertia) of the chopper in a way so you would get awarded for being careful and precise. It's less of an action game and more of a balancing act :) I might develop this game further and I've noted down all feedback!
