Very unforgiving - but in a good way. The controls a physics are consistent and there is no hand holding - so it feels more like a simulation style arcade game where the the mistakes are the responsibility of the person pressing the buttons. I wasn't very good at it, but I feel that making it 'easier' through automation would miss the point. It's like manually docking rather than pressing a button to do it for you.
I actually like the retro look of the quadcopter represented by circles and a square. I think that leaning into this type of aesthetic (maybe modernised slightly) would make the game stand out and be more unique than the use of pixel art and sprites.
Nice game!
