The game is luaAirForce and the homebrew developer claims that this is the first game that he has coded without the help of any tutorials and from the looks of it, he is going towards the right direction with this one.
Basically, this is a shoot-em down game and you have to annihilate as many enemy planes as possible. You have to press the up and down arrow to maneuver the plane, X for boost, and Circle to shoot them planes. Simple and amusing, but not necessarily perfect.
yoyomacy mentioned that he plans to fix some bugs in the game's next release. He says that he would be changing the bullet color, fixing the game over to main menu, and he also plans on making a fireball animation when an enemy plane is hit. Nice work, yoyomacy, we hope to hear from you soon.
