The flight engine is a GDK (Game development kit), it has many features up to date:
Simple spawning and AI
(Characters (planes) spawn in the same position
Unlimited planes, disappear at end of screen to free memory usage
*Note, when the engine is released , you will have to improve code snippets, change sprites to your game's criteria.
Thankyou for viewing the list, each day it will hopefully get bigger, until a beta or alpha release of the GDK is released.
