How's it going? There's a trial version of AppGameKit available to download here [
https://www.appgamekit.com/trial], that should help you work out if it's for you or not. The full version is often generously discounted on Steam so keep an eye on the price there to ensure you don't miss out on a bargain! If you're looking for something to read to wrap your head around some of the concepts that need to be understood in order to really get the most out of AppGameKit then I'd recommend another Steam item called The Official AppGameKit Tutorial Guide (available in Volumes 1 & 2), there is also a download called The Official AppGameKit Beginners Guide but this is just a slimmed-down version of the previous guide. These guides are provided as PDFs and can easily be moved onto other devices should you want to read them away from the PC. Happy coding!
