Here is a playthrough of the first world. It is unedited, but to save you some time (unless you want the entertainment), use the time links located in the video description and feel free to mute the video.
If you get stuck on the randomly generated puzzles or the puzzle race at the end, my only advice is to keep at it! They sometimes are the reason my videos are split because I had to take a break. They can take awhile. If you are on the first puzzle, feel free to restart if you aren't comfortable with the level.
Level 1-29 is separated from the rest because it took me almost an hour to figure out. The solution for that level is here:
Finally, level 1-30 is a puzzle race where you just need to beat another character.
