I think its ambitious to do every all by yourself when doing multiple games since it makes you not be able to give the attention and polish a game needs to be understood, accessible, and fun for the player. For example, there's no music, very little sound effect, and the gold minigame I could not even see the ball and thought the game was frozen. I would recommend choosing one of the mini games you like the most and giving more time to polish and to iron out the details gameplay
