Pilota

Pilota is a casual top-down flying game with an anaglyph 3D mode.
- Explore a large 2D pixelart world, or put on your red-cyan glasses, activate 3D mode with one click and watch your aircraft climb and pop out from the screen.
- The game has a realistic flight model: you have to take off and land, plus you need to monitor your speed, altitude and fuel as these parameters change during manoeuvres.
- You can try out 40 vehicles and do missions just like in real life: dust crop fields, extinguish wildfires, carry passengers, win air races and many more!
- A story unfolds as you buy new planes and unlock missions, but you can always pause your progress and fly for fun.
