And I enjoyed the game.. a lot. The graphics (for such an early Gb game) are great, the music as we all know is fantasticz, and the gameplay is just misunderstood I believe. It's like CV1's difficulty: Trial and error. While CV1 was based on you knowing the enemy patterns AND using the right sub weapons at the right places, CVA focuses on knowing item placement and on the whip. It's the same idea, different methods. I was surprised how much fun I had actually completing the game fair and square without save states.
Something to know is that yes, you lose the whip upgrades, but thats because of how the game's sole attack IS the whip. It makes you stay on your toes constantly, and losing the power up isn't the end of the game. Myslef and others I'm sure have always loaded a state after every hit so we could keep our powerup, but thats just going to irritate the hell outta you. Part of the game's appeal, like CV1, is the thrill of surviving seemingly impossible obstacles. I haven't gotten that specific CV feeling from a game in some years.
I find that CVA is very underrated. Yes, sluggish movement, challenging, and short, but it's simplicity is also a strong point. Its fun to pick up and try to get far. If you hate the game for the popular reasons, I'm not sure if I can change your mind, but at least try the game again, play without save states, and have fun with a game based on challenging you.
Plus, the little twist ending leading into B'sR is a nice surprise
