MWEB GameZone writer, Zaid Kriel, takes a look at Princess Rescue. Made by indie developer, "Sprybug" who created a port of the original Super Mario Bros. for the classic Atari 2600.
Now called Princess Rescue, the game is a compressed version of the NES original, featuring only 16 levels, where the original had 32. Other than that and the lower visual acuity, the game is a pretty faithful interpretation. The gameplay is largely similar and the audio sounds surprisingly close.
