The Hot Air Jr Demo is a demo version of Hot Air Jr released on May 2nd 2012. The game is a demo in that it is a beta version of Hot Air Jr. Although the level in the game is not an actual level from Hot Air Jr, the game served to test out the physics of Hot Air Jr, and for feedback on the game.
The Hot Air Jr Demo does not have levels, but rooms. Each room has a certain amount of stars, and usually a hazard.
This room has a star embedded in the wall, obtainable only through going through a non-solid section of wall in room three.
Hazards: Spikes, an axe
This room features a pit up spikes and an axe. On the left wall is a very small alcove. Going through this alcove allows the player to go back into the second room and obtain the star embedded in the wall.
Hazards: Spikes, six octopi
This room has a key at the end, which must be taken back to the first room.
Differences from full version
In the fifth room, if you collect the key and pop your balloon on one of the axes, you would get a game over screen. However, the balloon would still be intact and would act like it's still attached to the basket, despite having no strings. The player will be unable to blow Hot Air's child around until restarting the level.
