So it won't allow me to build more than one fort after I place one which doesn't make sense
Make it so you can do stuff before waves start
Music and sound effects work
Your asking 5 dollars for this? There isn't much hear and all the enemies are basically the same. You might be able to get your 100 dollars back but I think 5 dollars is a ripoff. Maybe make a better menu song, fix the bugs, and add more content. There is not that much here and if you want to sell you need to have something more than just 2 forts and 1 enemy.
