Slime Tower Defence

I am a 21 years old university undergraduate and this is the very first game that I have ever made in my entire life. Although the game is extremely simple, I copy code from the internet here and there, and the game may also have a bunch of bugs that I don't it exist, I still enjoy the process of making it. Hopefully you will found the game interesting, and please feel free to leave comment on stuff that you think I can do better on my next game.
