It’s a fun game but I would like to see the tank and plane depend on each other more so that it fits the theme better. Maybe you add a mechanic where you can pick up your tank for a short period of time and then you can use the tank in the sky and then add enemies that fly that need the firepower of the tank. Other than that, I think you should improve the graphics and audio. Anyway, I think you did a good job for 48 hours.
