Pros:
- The concept is really cool in that is a simulation with a game aspect. I liked this.
- the physics are good and I guess this is the best way to control it
- The simplicity of the design
Suggestions
- I think the camera should be farther back from the drone object. I found it quite difficult to judge depth when trying to land the drone on top of the box.
- Sometimes I landed on the box and it worked as intended, however, sometimes I landed on it and it wasn't trigger. I think you should double check the box colliders size.
- I did find it really difficult to land on the boxes to be honest, but that might be my lack of drone experience. It's unusual to use both sets of arrows (WASD and normal arrows) in a game but I guess that is what its line on a drone controller. perhaps making some boxes bigger would help, or maybe you just have to fly through them instead of land on them
Overall, I played this for a while and its quite cool!
