The simplicity and the art style - I am astonished that they even had thought in 2000 to give this game such and aesthetic.
After playing it again today, I feel like most of the games I played don't even compare with the emotional weight this carries for me and aren't half as rememberable. Playing a lot of games through these 14 years of not touching this Scooby-Doo game made me realise how simple a game can be to stick with you. I really can't belive how excited I am to play it to this day and how much I like it. 14 years later and here I am, found the game, installed it, ran it in Windows XP compatibilility mode and there I was, a small time travel to my childhood memories. I had a blast with it and I can really remember how scared I got by the masked figure that appeared once in a while when you clicked a wrong thing.
I played this game in 2007, on an old PC that barely functioned at by grandparent's house.
