It was tremendously exciting and fun! I got all the achievements!
When I first played it normally, I struggled with the progressively more difficult platforming and demon placement, and died many times from the sheer strength of the Raijin.
In the “Oni-no-Kill” game, I had to carefully maneuver to avoid the demons and also enjoyed the feeling of a puzzle game, and when I cleared the game, I had a great sense of accomplishment.
The no-death play was also very tense and fun, especially when I learned the boss's action patterns and safe zones, and the real boss battle after a few minutes of climbing was very tense.
And the beautiful pixel art, the way the physics worked in blowing up when you died, and the great music (I felt the bass work and become a bit more disastrous after the demons appeared) was tremendous!
This was a really good gaming experience. Super amazing, meow~!
