The game borrowed a lot of elements from legendary games of the nineties so that during your many adventures you will encounter references to games like Ghosts and Goblins, Street Fighter II, The Legend of Zelda, Castlevania or Metroid.
The reason why 'I Wanna be the Guy' is more well-known, however, is not for its multiple references to other games, but its terrible difficulty. Throughout the many scenarios that you have to overcome you will find traps placed with the objective to kill you over and over again.
For if the design of the levels is not complicated enough, on top of that your main character is quite weak. The slightest touch of any element of the scenario will end his life, making you go back to the last checkpoint where the game was saved.
I Wanna be the Guy is a platform game both fun and legendary. It's one of those challenges you like to boast about once you've overcome it. Although of course, overcoming this challenge will cost you blood, sweat and tears.
