A simplified version of a clever game that, despite its wonderful colors, animation, and core mechanics, had no mercy. I assume this game is the result of parents buying an adorable, simple-looking game and finding out how unsuitable it was for children the hard way.

While it can help ease the player into new mechanics with simple exercises, Primer rather egregiously does not function as a stepladder to the original's difficulty curve. When switching from Primer to the original, I found a noticeable gap in difficulty between the former's final puzzles and the latter's earliest. I hate to rag on an IP I really enjoy, but Primer seems to fail at its sole purpose as a preparatory companion piece.
