I will beta test for you. I will soon have smileBASIC on a 2ds and n3ds if that ever becomes relevant to your development.
I also saw your game request. I will try to make a basic caterpillar style game for your app.
The features will be preinstalled games. But I'm waiting for somebody to give permission to use it in the os. After at least 1 game is available I'll add it and release build one. I'll also fix th 1.4 bug starting at notepad
