Thanks a lot for the feedback! I had hoped to expand a second turret type - a soap cannon - which would deal more splash (get it) damage. I get what you mean about the slots that are better. One of the comments from the mini-showcase made me think about that first turret a lot so I built up the terrain a bit more. I had hoped to put in more scenery which could be very tactically placed such as rocks, boulders, trees etc. I had also planned on having certain nodes cost more or have to be 'unlocked'.
I love the idea of forcing the break in social distancing! I'm intrigued by that so I may add that in when I revisit the game.
Thank you very much for the game jam, it has been a lot of fun!
