Wow, great words, thank you very much. It's an honor to know that you can feel the Castlevania essence in the game. Specifically I based it on Super Castlevania IV. I also wanted to implement the mechanic of hooking with the whip to points on the stage and swinging Tarzan-style, but I didn't have time :(. In future updates I want to implement it
Thank you also for commenting on the walking animation issue. I will investigate from what you tell me and I will polish it :).
By the way, I already rated your game a couple of days ago hehehe. Great game with Metal Gear style, and with the Spin theme well implemented. I loved it.
Cheers!
