I have 2 issues with this game...
first being the precision to make specific landings while dodging on either stages and bosses (The dragon boss difficulty is absurd, you require chirurgical precision to not land on the fire, and the fire last too much for being fire on paviment), the chaman demons healing enemies just makes things more tedious than fun, since they end up healing themselves and you have to either rush towards waves of enemies in order to hit them, which risks to get multiple hits.
second is about the control response, as it seems that it has a delay of 1 second to repeat the same command (Such as dodge or jump), while the bosses' response is almost immediately (Like the hand boss or the whip ghouls) and during a dodge you have no response until you finish the animation.
the game is good, but this things kinda ruin it for me, since is absuredly hard, is hard for the sake of being hard, not for the sake of challenging, take for example Bloodstain, it has enough difficulty for casuals and hardcores to play it and have fun, but this game almost rivals with the difficulty of Ninja Gaiden 3 of NES.
6/10, rework this aspects cuz the punishment shouldn't come from not being milimetrically accurate or just spawn enemies for the sake of spawning enemies... but by mixing patterns and failing to read the opponent's movement (Like jumping when the enemy is shooting a straight projectile) (The A. I. should outsmart the player and not the game should put absurd situations).
