The game was difficult to understand in the beginning ( also due to the color of the browser which is not understandable). Once I understood that the controls were both wasd and arrows it was better.
Maybe a better start menu would have made everything more understandable.
The other thing that I couldn't do is that I couldn't take off at the end, no matter how many times I clicked enter.
The game is very original, the 3D top view is something that I was not expecting. Also the possibility to play as 2 players is interesting and fun! keep it up!
