All in all, great fun if the bugs were not. I knew from the Megabug the dragon room in advance and am evaded him, but there was still a lot of other bugs anyway. When Spell learn from Wingardium Leviosa equal to the first, the level could not finish because the armor despite proper assembling his action simply did not want to carry that level worked only after repeated restarts. The mandrakes level had to be restarted three times been to the handling mandrakes activated. Defeating the spider Aragog worked after a restart, as it was before imun on the attack of spiders. It is also the Harry Potter character for some reason not possible to learn all spells, although with him all lessons (Riddikulus not work) were visited. I do not know if all these bugs only occur in my game or are generally available, but are permanent but really annoying.
Without the bugs 5, so only 4 stars. Still a great game, my buy recommendation is there.
