Seems like choosing the camera was the easiest, here is the walkthrough for it.
1) Choose the Camera.
2) Go to where the Prism is and rotate it until the color of the room turns purple.
3) Go to the room which has a bag of compost and take it.
4) Move to the room where it has the chemistry apparatus, notice that an outline of a key is visible. Take a photo of that outline.
5) Move to the Transmat and put it in order, 1st should be the photo, 2nd should be the compost.
6) Press the button and a key will be produced. Take the key.
7) Go to the place where the lock is, then use the key on it.
Congratulations, you have successfully escaped into the sewers!
I'm not entirely sure if the item you choose in the beginning decides if you make it out or not, contrary to my thoughts in the beginning when I chose the camera and couldn't figure out what to do. I managed to get out with the power core, but a lot of the stuff in the room went unused so I guess you can make it out with other items too.
I was not that entertained by this. I think the weirdest part was how I was not really able to understand how to even pick things up. The animation seemed pretty bad too. I guess the music was alright. There really was nothing too terrible about it. It was a bit mysterious.
I thought this would be a much cooler game. I was just turned off by how it unexpectedly became a point and click adventure game. Well, it always was, but I felt like I was duped. I can learn to appreciate all things, though. It just did not interest me.
GET THE PAPER AT THE BEGINING AND MAKE THE MOG PIG THE CODE IS ON THE PAPER.
AFTER MAKE THE FRUIT PLANT WITH THIS CODE A10 T30 G60 REMEMBER IT GROWS IN INFRARED LIGHT.
USE THIS FLY TO POLLINATE IT THE CODE IS A20 T70 G10. THEN FEED THE FRUIT TO THE PIG. HE WILL SHIT. PICKUP HIS SHIT!!! NOW GET MORE WATER IN THE BEAKER. NOW DROP THE PIGS SHIT IN BEAKER OF WATER. NOW POUR IT INTO THE LAB FLASK. AND PLACE THE BEAKER AT THE NOZZLE. IT WILL FILL WITH GREEN ACID. USE THIS ON THE PAD LOCK ATTACHED TO THE SEWER GRATE.
Fun and very challenging.
I started the game with the power core, and instantly I was lost. I went around and did what I could and tried to figure it out the best I can. After a few hours of getting now where I looked up the walk trough read a bit and I was astonished on how easy it was to solve the puzzle.
Good work my friend, good music and wonderful game play. Awesome in general and amazing overall. Good work, keep it coming with more.
