I also think it could use an upgrade system? Like each level you gain XP and coins and stuff when the die so you can upgrade vehicles and people and buy new things
i like it, but it needs some new walls, (like curves and stuff) Elements like water fire lava Etc. People, Lighting, and a few others but you'll figure it out haha
I think its good but you should add a few things... like a boat, a multiplayer, Different levels, More weapons for your single player body, a way to change controls, add ways to rise and lower the helicopter, a transport helicopter, map maker, allies, chat for multiplayer and a few more things but other then that its an amazing game, oh and different views
Can't really do a minimap, it's generated randomly as you fly!
