Haha they're definitely portals of doom! If we expand the game I'd love to make them into spider nests :) The game is all built in a single screen (or scene?) in unity. Thank you so much for your kind comments!
Spider nests is a cool idea!
(I haven't worked in Unity yet so I don't know the terminology.)
Don't worry me neither! I'm responsible for the art while my teammate, managed to make everything magically happen behind the scenes :D
