Thanks for your feedback :D
The minimap was really easy to implement, and I though it would be too difficult if you didn't knew where the enemys were. Same thing for the steering, making it faster would made the game too hard... I should have give more control, like air brake to slow down as someone else suggested.
For the menu, I like when the game feels more "complete" ^^ but yeah, definitly not the most important part.
And for AI, actually, the current code is really simple, I guess my mistake was to use a tool I'm not comfortable with...
Thanks for playing :) I hope you enjoyed it !
