I know it not made in B4A (have not tried that yet) but its made in Unity.
I just wanted to show it.
It's a game where you must rescue men from a burning tower. The more men you rescue the faster it gets.
And there is a online leaderboard so you can fight against other players.
Sorry for not clear writing.
Your game is "simple" 2D game with a few graphics but the file size is more than 20MB. I know it's huge because Unity engine. I'm sure you can re-write by using B4A GameView and the size will be reduced a lot.
Will give it a go later, looks like a good game from the screenshots.
But susu is right, it's best to use a simple engine if the game is simple, to keep file size down and make it more compatible with lower end devices. LibGDX is a good compromise, it gives you a good game engine and only adds about 3mb to the filesize, although gameview would get that right down further.
