In a sense, I suppose it was. I used past experiences from some of my other games and I've been wanting to make a good turn-based TD game for a while. I sort of made one before, but it had very different mechanics and I didn't like how it turned out. This was just another experiment that seems to have been a success!
And yeah, it's a "Once you get it, you get it" sort of thing. Which seems to be a theme with every strategy or tactic game I make. lol
Thanks for playing though! :D
