Disclaimer: I only tried the campaign as I didn't have anyone else to try the versus with.
Overall a very cute and fun game. RTS games are always a risky choice for a game jam due to the number of systems to build and consider, but I think you pulled it off quite well! Music fits the game really well, I love it. Art style is simplistic, but fits the game well. The game in all feels very well polished. Kind of reminds me of those flash games I used to play! Controls took a bit to get used to (but I suppose that goes for any RTS game though), but after a bit it started to feel very intuitive.
Pretty impressive result!
