Bloons is an awesome series and I can see that you've put effort into making this.
I understand you're saying it's "incomplete" version, but https://i.gyazo.com/9c41ce87f3bcd0fc9b8dfc2d8526ef10.png come on dude. You should at least learn to take graphics from elsewhere properly. :P
I'd highly suggest you to learn to draw & animate. I think that's what I like the most about game development - being able to put your(emphasis on 'your') art together and make it interactive.
Good luck on your further projects!
