I was about to give up on the first level with the idea that "something was wrong" when I read that the objective was just to survive as long as you could lol
A timer to show the best time on level 1 would be nice!
Level 2 is cool, but again, some cue regarding how close to the end would be nice.
Level 3 is the funnest, the first three times I just died without even understanding what was happening, but got the chopper in the fourth run (really a RUN!!!!) lol
Keep up the great work!
