definately clickableCorona SDK is a android compiler that allows for very easy game / app making with almost no effort. It has its own physics engine and uses the dynamic very-easy-to-learn Lua language that GMod and many other games use.
I made
this game with it and it was very easy, you can find the link to the github page about this app here:
https://github.com/Tanashii/massive-octo-wallhackThere are a few plans, the first one is free and allows for app making and publishing it with ads or IAP

The rest of the plans are expensive as forget so nobody ever buys them, but they're there
I know that I'm going to get forgeted on because of this thread but I just wanted to tell you guys about this sdk :c
