Thanks a million!I was actually planning to place down arrows with a marker on either side of the screen to warn the player, but being a game jam (and me annoyingly not begun making the game for the jam until a day after it started) didn't end up having enough time before the deadline hit; sorry that you ended up losing cos of this :(
To be completely honest, I had in fact at first coded in a PID controller for the drone, which would help the drone to be more stable in one tiny location, but decided that would -- and I quote myself -- "make it too easy" XD (turns out not an amazing idea when the game is too difficult for a lot of the game's audience, but oh well!)
Thanks a lot for the feedback, and I'm glad you liked it!
