At the very least there will be some patches to fix bugs, balance, a Concept Art gallery - as well as any content that the art assets were done for but I did not implement in time. One of those assets is another turret, I just need to finish the VFX for it.
We did have plans for more content, but it was cut during the jam to meet the deadline. The team put some heavy work into the game over the last month, so letting everyone rest up a bit, and then see if they'd like to continue it!
