If you do not know, The Runthrough was developed by Djek Studios Interactive (Hugo Peters) as a learning experience for him to get better at game development, making in the process a free version of The Impossible Game.

The version 0.0.2 had these levels, in this order:

1. Chaoz Fantazy

2. Flying'n'Stuff (Runthrough's exclusive level)

3. Heaven

4. I Seek You (Runthrough's exclusive level)

5. Phazd

The sprites that you see on the screenshot are not from the game, but rather recreations that I made using GIMP.

I wanted to include this amazing game in my project since it was the first game of this kind I played. You can change between Impossible Game and The Runthrough in the game's settings.

Also, The Runthough's development seems to be stopped, I do not know the reason why of that.
