Short but full of fun potential. I like the RTS style gameplay, I could see you going really far if you decided to continuing to invest in it. In my experience, games like this truly thrive on the amount of creativity you give the player, the feeling of building a society and expanding your units makes for some great gameplay.
If you continue to work on this after the jam (as it looks like you will from the ending message), please let me know, I'd love to play a full build of it!
