No crashes for me. But mechanically, I can't seem to do anything right in the game. I can only create a single web string, and I can't seem to interact with the flies in any way.
Actually, you can create multiple webs. Each web costs 25 energy. Flies will fly in random directions (after pressing the start button). If their final point intersects with a web, they will bring you 5 energy; otherwise, you lose 5 energy.
