Hey, thanks for playing and the feedback! I understand that you want to be able to move and place towers at the same time, but the reason it works like this was cause I wanted to be able to play the game without using the mouse (so A/D is for selecting towers, space to confirm, E to cancel). Also I felt like since the player is a character and not just a all seeing god I wanted to make sure the player has to move around to place the towers and such.
Glad you liked the earthquake mechanic! It was actually the idea of the earthquake that spark the entire project. I got this image in my head of how a grid could be split up like that. Then after a bit of thinking I realized a tower defence would be the perfect fit. (First I was thinking like automation games where earthquakes would split up your production lines)
Thanks again!
