Nice! I liked your game and I thought that the pixel art looked great!
About starting multiple games, I'd suggest to you to work only on one game at a time and write all of the ideas that come to mind on a text document. I found that if I jumped to make a new game each time I got an idea, I would never finish the game I was currently working on.
I also found that not all good (or even great) ideas turn into good games. To avoid spending time on these ideas, I have made a different text document called "Spitballing" for ideas that come to me (mostly late at night) and that still need to be seen if they can be converted into actual games.
Good luck on your games!
