I think it's awesome that you used a new game engine for this!  I always tell myself I'll learn to use one of these game engines, but I feel if I tried to do it under the pressure of game jam time constraints (and design constraints), I likely wouldn't get to submission.  So kudos for getting something done.  

FYI - You're likely aware, but the game renders differently on different platforms/screen sizes.  On my phone I see way more than the "playing area", whereas on my PC, the bugs and circle sometime wander off screen to the right and downward.   

Anyway, congrats on learning some Godot!
