DERE EVIL EXE is both a terrifying thriller with a gripping story and an unorthodox retro platformer with unique puzzles and obstacles. In DERE EVIL EXE, you step into the tiny shoes of a silent hero named 'Knightly'. Knightly must jump, run, and manipulate environments in order to survive the heart-racing journey through a stunning pixel art world. Within surreal structures lurk dangerous creatures known as 'corruptions'. They take the form of their creator's greatest fears. Their creepy creator, sporting a cunning visage of cheerfulness, hides in plain sight as she watches her prey fall deeper into her traps. Will Knightly be able to escape these pixelated nightmares? ===== “Take the challenge, and wade in, DERE EVIL EXE is unquestionably worth your time... 5/5” - Touch Arcade “An indie title that shifts from retro platformer to meta-horror, it pokes fun at and toys with its influences along the way.” - Rock Paper Shotgun “DERE EVIL EXE is yet another great game from AppSir we really enjoyed... 95/100” - Edamame Reviews ===== EERIE AND EXCEPTIONAL Finalist in the 15th annual International Mobile Gaming Awards and nominated for Best Storytelling in the 2019 Mobile Games Awards.
