This is just the early demo version that doesn't include all the content, unfortunately. I need to fix the bugs first and then I will work on adding more content, like tower's global upgrade system and more abilities, talents, enemies, difficulty levels, etc.
I will be posting the updates here in devlogs so you can follow the page if you want to.
