@@Spoiler Alert@@
I DAMN LOVE THIS. Very, very, very well done. I hope you make more. This needs a save game feature though. To quit back to the main menu from inside a level, press ESC (I only figured this out just now)
Anyway, here are some tips you might like on the various levels.
LEVEL 1. After you climb the cliff, go right down into very bottom of the valley. and there is a larva. Pick it up and stick it to your head before you leave.
LEVEL 2. Beyond the cliff there are a bunch of rocks hanging in midair that you can climb. At the top of one of them, there's a green switch you should press. At the top of the other one there is a blue fly. You should catch that fly--the best way is to spin webs all over the place (pick up a foot, press ctrl, stick the foot to a surface, then move and the web will follow you. To stop making web, hold space and move a foot over the web to grab it. To cut the web away from your body press ctrl again). Then hold the fly in your mouth and fix a web to the ground, and you will float upwards--there is an island in the sky with a larva on it you should get. Grab your web to keep yourself from floating into the spikes.
LEVEL 3: String a web across the tunnel and chase the fly into it. Then pick up the fly and put him in the keyhole.
LEVEL 4: Just swim, stopping at a bubble when your air gets low. There is a larva you should pick up, and watch out for a falling boulder.
LEVEL 5: Go to the ceiling on the right and get your larva. Fight the bugs, but your main goal is to tear out their nest--just grab it and swing it back and forth until it breaks. If you can't break it, then don't bother (you don't have to). Hit the button and leave.
LEVEL 6: Get good at rapelling. This level is the most fun level. You don't have to rappel by the way to finish this--if you do it right you can swing from the underside of a platform onto the next one without using web. There is a hidden larva beyond the spikes above your starting position--to get there, and get back, you have to be clever with flying (catch a blue bug and do like in level 2, only it's harder). Also, if you leave your egg sac behind (you can stick it to some web so it won't fall) you can climb all over the huge pink monster at the left, which is kind of cool.
LEVEL 7: Just some flies to catch and keys to insert. To get past the first part, grab the dangling bit of flesh and swing it until it turns red. Two things should be noted: the green thing that's made up of a bunch of cells and is floating in the pond is useless, but be sure you do not eat it (poison). The exit is inside the notch of the sideways Y-shaped rock formation in the last chamber--toss your egg sac in, then follow behind.
LEVEL 8: There are some more fleshy dangling things, which will open a door in the center. But before you pull on them, string a web across that door--two larva will fall out when the door opens and the web will catch them. Don't fall into the acid below. It may be better to leave your egg sac behind on a web here before you go into the final chamber, where you will have to fight some more flies. To rip out the heart, grab the three red nodules on the arteries leading into it, and rip those out one at a time. Be careful that the heart doesn't fall on you.
