Not a bad idea. Excellent balance. But the typical trouble of many novice authors in this genre. Love of animation coupled with a bad engine. At first, while there are few falling objects, everything looks good. But at the end of the game, even if only the game is running, the FPS drops to 12-15 when a large number of objects fall out. And if you run, say, an audio player in parallel, so as not to engage in meaningless clicking in silence, objects on the screen begin to teleport.
