Loved the art style, the music is also cool! I would've liked for the tornado to either move faster (i know there are upgrades) or have a way to redirect it a little. Basically anything that would give me extra "participation". You could also add more buildings and add some good sfx to make it really satisfying. My patience was struggling waiting between each tornado spin. Maybe also a health bar for each building would've been also really nice to have. Great job though!
