How great if more puzzle games were like this, if you need a minute to think - just start blasting. My two ideas here I'd like to share would be 1) mapping the map pan to a right mouse button hold so the player doesn't need to bother with their keyboard. The second is more work, but I think some Classes could be good here. Button pressers could be reskinned as engineers, then there could be soldiers who handle combat and shooting, and maybe a medic who helps mend any wounds. Also gives an opportunity to add some story and character. Puzzle tactics might work as a genre, who knew? Felt innovative.
