Day 9. I have submitted my project. A lot of fun little issues i didn't realise i would have to deal with when i exported. Was hoping for 1:1 but had to compromise.
I added 28 more waves of enemies (total 35). 32 extra upgrades totalling 59. Enemy hp bars for the big guys and just so much more. Glad to have this done. Please check out Defending Fort Kenstone
EDIT: And i have just fixed a game breaking bug i somehow didn't notice. It is a bad idea to have 20 different enemies scan 500+ objects every frame. Resolved now.
