The Apprentice

Map layout

CD-i may not have the best reputation according to 'the internet', but that doesn't mean there aren't any good games.
The Apprentice is one such unmentioned gem. Personally it's my favorite game along with Dimo's Quest!
Each map has three layers; the first two are (mostly) static, and the third has the action codes. These can be a collectible item (coin, key, food), or a moving platform/hidden pipeline (and its path), or an enemy. Basically anything beyond basic a platform!
