Here is an excerpt from Helltaker's Steam description:

You woke up one day with a dream. Harem full of demon girls. You've opened the portal in hopes of fulfilling your wildest desires. Hellfire burns through your lungs, death awaits around every corner and everything looks like from a cutesy mobile game. You are in hell.

• Win the hearts of horrible demon girls.
• Kick adorable skeletons around.
• Solve puzzles as efficiently as possible.
• Or just skip puzzles in the menu.
