-Player 1: WASD, as usual. Q to fire, and Z/C to change altitude -Player 2: Arrow Keys. M/L to change altitude and K to fire. -Altitude on the top, health bar right below it. You can crash into each other if you're close in altitude, so don't.
This is only version 1.2. I'm planning on actual plane sprites, bombing, COM, etc. If you get to high, your plane will stall, to fix that press Z/M, then C/L. (Depending on the player) sorry about the weird control layout for Player 2
