I tried eating the poop thinking the key was inside... It wasn't
I couldn't get past the blue and red block part. I sorted blue into the barrel and red onto the red block but that didn't do anything. Then I tried the reverse but that also did nothing. I suggest reducing the number of blocks or adding a bucket to make sorting the blocks less tedious. I ended up using the Cinnamon roll-looking things as plates to carry multiple at a time. Also, the pass through the wall should at least be transparent. Otherwise many people will think the game is over after getting out of the prison cell.
Update: Had a second look through your submission page and decided to try again. I think I did it right because I swear I hear a noise but had no clue what to do next. I couldn't find the blue key.
