"Don't Look Back is a retro styled platform game playable through Adobe Flash and designed by Terry Cavanagh. The game is a modern interpretation of the Orpheus and Eurydice Greek legend.
The game is a combination of two ideas; Cavanagh wished to create a "silly shooter" where the player's actions were "redeemed" after being shown from a different perspective, he also wished to create a game where the gameplay acted as a metaphor of the player's actions.
Critics praised the game's addictiveness and presentation, but had different opinions over the game's high difficulty level."
