The game looks great, very polished. I really like the idea; however, I found it pretty hard to control the drone seamlessly, and it became quite frustrating over time. Nevertheless, the music and art make this game unique. I just can't forgive myself for killing so many poor animals...
EDIT: I get used to the controls and the game is great. Gameplay loop is super simple, yet entertaining. The only thing that I would like more is content, more animals, more upgrades, different levels with multiple lanes, different types of drones aka character classes, multiplayer (haha, yeah, I know). Great game!
