I didn't expect that you will be collecting apples in that "certain" way. I will be honest...there isn't much development you can do in this game if you want this to be only an apple-collecting simulator. I would suggest adding multiplayer (because multiplayer and pvp makes any game better...we all know that). Maybe a multiplayer mode where those apples are bombs? A horror mode surrounding apples or Poland? I mean if a person knows coding, then he/she can do nearly everything.
Now about this game, a person will play it 2 times (I did). At this current stage, I cannot say much. It is a great apple collecting simulator (maybe you can incorporate the lives of farmers?). The process of collecting is unusual as well.
