OK I'm going to give you some tough love...
First of all, you clearly did not play test your own game. How do I know this? Because there is an impossible segment in the NCE room where a block is lethal if you touch it, and you have to touch it in order to proceed.
See the picture here...

The death effect is the same death effect, and maybe if that was the only thing, I could move past it. The Dodopachi music....OK you didn't take the same track he did, but its also been used in another bad medley (that also tries too hard to be K3 Break the Series Z)
The screen choices.
You do realize that in a fangame universe of over 2000 games, there are literally 10's of thousands of rooms you can pick from. You took the literal exact same screens from the stage 1 of K3, and put them, into your stage 1.
The "Orange" rooms are a complete disaster. We know what the original versions of the rooms looked like. We know you added the silly traps that force the player to basically die their first time through the room, then repeat the most tedious ladder segment in history. Why? These add nothing to the game at all, and removing the save point from half way through the room just completely shatters your difficulty curve. The rooms afterwards "Box Trap" are a walk in the park compared to it.
You really need to ask yourself if you are just trying to make a game that already exists, or want to make your own medley. I love medley's, I helped make Culture, but please stop taking all the same rooms, music, death, etc from that other game.
Sorry if this sounds harsh, but I feel this needs to be said. Your production value is getting a lot better with your games, but you need to start thinking more about the actual content.
