Right, my PB is 4:19.59, so I'm not sure if this is the most optimal route. Here's my strat;

1. Start the game. The timer starts when you select a language. After that, it's roughly 20 seconds before you can actually do anything.
2. The letters To start, just spam-click the "o" in "no". After you do that it should fall down. Next, you have to pick it up and drop it as fast as you can. You should see a white box starting to peek out from the top right corner. When that falls, it becomes a sound icon
3. Sound The sound icon you just dropped from the ceiling? Click it and it should mute the narrator. Just do this a total of two times and then he puts up a wooden barrier. Use the "o" from before and drop it on the wood. Then, he covers it with metal. Take the metal box and drop it. It should make all the letters fall down. Click and hold to loosen both screws and a panel should pop up.
4. Building words Here's where you can choose. You can either spell "game" and move on to part 5 OR you can spell "goat" (that's what I do) and then spell "game" OR you can spell "tree", then "goat", then "game". If you spell other stuff, make sure not to click the arrows.
5. Breakout. When you spell "game" it should automatically scroll you over to the left, where there's a version of Atari Breakout. Same rules apply, just use the paddle to break the bricks. Try to do this as fast as possible, because you can't advance to the next voice line until you get the "stop hitting the bricks" line. Then, everything is straightforward. Break the bricks. When you hit 4000 points, the glitches will start appearing. Then, he'll start talking about things to put in a bugged creation. You need to pick up the trophy that you get for winning BEFORE he finishes talking about goats. Just click and hold the trophy and drag it over to the arrow on the right.
6. Trees Now, if you only spelled "game" then spell "goat" and "tree" (it's faster in this order). If you spelled "goat" and "game", spell "tree". If you spelled everything, good for you. Take the trophy over to the right and enter the goat room. Fill the trophy with the waterfall and take it back over to the tree. A squirrel will fly above. Drop the trophy only AFTER the narrator says "a squirrel!" not "the key". Do this 3 times total and then click the up arrow to get to the tree. There's a nut hidden in the bottom right of the tree. Click it a bunch to make it fall down. Use the big metal box to break the nut and give it to the squirrel. The squirrel will eat the nut and drop the key. Use the key to open the goat cage.
7. End There are about 30 seconds of dialogue here, but press whichever (yes or no)(I usually hit yes). The timer stops when you select yes or no.
