2D platformer tutorial
Fairly outdated by today's standards, but there are some neat things in here like the cool particle effect for the rocket or how to use trigger colliders to produce footstep sounds.
The main character in this tutorial game is called Lerpz and was the mascot for Unity 2, if I remember correctly.
The tutorial itself is probably a bit hard to follow now seeing as it was made for Unity 2, but I've verified that the project works in Unity 2.6.1 which you can download from the link on the right. The original tutorial and the project is also available for download on the right.
Disclaimer: This project is no longer officially supported and it is NOT for Unity 5. Most likely you'll get no support from me either, just use take it for what it is.
