You definitely did make the game feel like Ghost 'n Ghouls, not much like Castlevania, and oddly enough like Ninja Gaiden except for those dickish birds who always spawned midjump. *grumbles*
However, I do have to agree with a lot of other players on this one. Where the original felt a lot like a good defense-type game, this one strayed a bit too far from the formula.
I enjoyed the fact that there were only a set number of enemies, I didn't enjoy that pretty much after your first step they would immediately start to home in onto your position.
The weapons are indeed broken, and in need of a fix. The Shuriken was my personal favorite; in games like these, I would prefer a weapon with faster attack speed and a slight arc to those of much slower, but heavier damage output. Everything else pretty much wasn't worth my time, seeing how the weapons either have a slow attack speed (the Knife), move with you (the Boomerang), or are an anti-air weapon(the Axe) when a vast majority of your enemies are on the ground.
Ghost 'n Ghouls also had a life system in place. You died, you would restart at a checkpoint or the beginning of the stage and your lives would go down a notch. I think adding that may help keep the flow of the game going rather than having to die once, restart all over again, and learn from the mistake.
All in all, an average action platformer, but in need of some refinement.
