Very good gameplay. It feels well balanced with the level and upgrade system, and I like how more enemies spawn as you lower the temperature of the sun while the music becomes more tense. That synergy really adds to the atmosphere. The concept of trying to put out the sun with just water is bizarre in a interesting way. I guess the ice age would be next if you succeeded, but hey, real life science doesn’t have to apply in video games. No real complaints here, solid game!
