I'd recommend this. As kids my brother and I could never complete a game on the BBC Micro called Imogen[0]. It was amazing for the time in that your character could transform into three modes (wizard / cat / monkey) and on one screen a fourth mode, and the transformation looked smooth even back then. However - we never completed it. As an adult I found it again and while I completed it fairly easily, it was a nice memory.
