Nice turn-based combat! I managed to destroy the enemy city in the 2nd try :)
I understand the game is made with Vulkan. Did you make the entire engine from scratch??

Yes, but not inside the jam time lol!, heres the code I wrote which I used for the basis of the jam game if you want to look at it: https://github.com/NoamZeise/2D-Vulkan-Environment (although its not really made for other people to use)
Bacially just allows for rendering textured quads, fonts and audio. So i wouldnt go so far as to call it an engine.
Thanks for giving my game a try!
