Nice visuals, and the idea is good, but i found some issues that I think you might want to know!
As far as I went, all you needed to do is to hold the spacebaar and nobody could hit you haha, its really too much easy so its not so much fun.
You should try to implement restrictions to force the player, or maybe other types of enemies. Maybe flying doesnt really add that much to the concept and you should stay with a bug that doesnt fly and just changing layers.
There are other minor issues that you could check, like the bug its allways printed in front of the people, even if its in a further layer.
In anycase its awesome that you managed to make it for the jam! Great work!
