Game-ideas from Youtube : part 1

I just watched this video, about a tiny leaf collecting game : link

And i really want to clone/implement a similar design as an exercise for learning godot/blender with the following improvements :

1.  Add a tiny achievement or goal or quest system  : ex: collect X type of leaf ..etc full inventory of common, full inventory of rare ..
2.  [either U.I button or mouse action] Option to kick the tree once in a while which will make a bigger drop (a spinner will show how much time you have left until the next kick) 
3.  [UI button] Option for fast forward time skip ">> x3" or something for short burst of faster game loop to not wait for eternity (and also for debug purposes)
4.  Make the leafs behind the tree glow-y and the  tree a bit transparent (?) like a cs-wall-hack effect.
