I couldn't figure out how to proceed through the game but I did figure out how to use the tempura cannon to create a staircase up to the second level. I tried to esape through the window but no luck!
You have to connect the two police-light looking objects with a strand of tempura. I plan on posting a spoiler/instruction video soon because a lot of people are getting stuck there :/ Thanks for playing!
Edit: Just added a video to the page if you're still interested.
