I loved this game. The art was great, especially the cutscene at the beginning, and the sound and music fit quite well.
The gameplay was really fun, I enjoyed how fast paced it is, and I found that the controls actually felt good, they were not 100% responsive but that makes them feel more realistic in my opinion. I felt that maybe if the helicopters spawned at random heights, the game would have been a bit more challenging and fun.
The game was also quite polished, I found no bugs in the game... well, except the mosquitos of course :D
Overall, great job with the game. Good luck in the game jam!
