Another thing for all of you having trouble with loading this game just Right Click and click Play and then your game starts without refreshing the page
I hope this helped!
Well Done I actually never thought that the clicking is possible either you had little programming materials but I'm going to suggest this for game creating here is my suggestion --> Construct 2 is what I use to create games and there is a load of tutorials and I am using a tutorial to make a Tower Defense game there will be 2 ports of it A GameJolt version and a Kongregate version and here is the official link to get it plus it's a free program --> https://www.scirra.com/construct2
I hope this helped and Enjoy!
