Hot Air Balloon Flight Simulator is a free flight simulator game that will let you experience the very first moments of the aviation industry.
As a hot air balloon pilot, your main goal is to collect as many stars as you can in the game, so you can fly to the next level.
In order to collect the stars, you need to fly through the clouds, which will be a really difficult task, since the clouds are extremely dense.
If you manage to collect the stars, you will be able to unlock the next level.
This game will also let you pilot an airship, which is an inflatable balloon.
