Slightly off-topic: I personally started using Solar2D native so that I can implement the whole levelplay apis myself for my app (or any other apis). It took me around 30hr of work for ios version, including setting up a solar2d native project for the game, all the xcode settings issues, downloading levelplay sdk, levelplay dashboard setting, ad network registration, writing obj-c bridge code, and finally calling from the game in lua to make it work. I had no prior knowledge of xcode or native project or ad networks, and I thoroughly used AI. Without AI, I probably could never manage to make it work. It will probably take me similar time for android version again.
