Save Your Momma

(Note: sorry! the starting cutscenes are quite long -- please just wait through them, the game (hopefully) isn't broken!)

Once you've amassed enough flies, select your chosen spider from the bottom of the screen, and drop it at the location on the web where you'd like to place it. Click 'Esc' to undo your selection if you change your mind. It'll do the rest of the work to defend your Momma. 

Remember that some spiders can only go in certain places (shown by the red/green indicators), and you can only purchase the ones you can afford! 

Don't let them get to your Momma.
