wtf is this game and why is it that hard on easy
Depends on your definition of hard, if you are lost don't know what to do then I agree with you. You can easily get lost at some point of the game in your first few playthrough.
In terms of gameplay, it is rather "mastering game mechanic" it is quite annoying when you not familiar with the control. Basically just stay naked throughout the entire game. When Vena is wearing clothes, there is no way of douging ghost grab. Once Vena is grabbed, she has a very short time to free herself and at the sametime her health decrease. However, if she is naked once she is grabbed she still have chances to free herself by pressing the right arrow key (depending on the progress of the game, it vary from 1 to 3 keys need to press), just keep it slow and press the correct button and she is free.
There are few areas are quite annoying in which you may need to retry few times. First is the skull ghost, that area there is no secret, just keep safe distance and try to avoid the skull hitting Vena by walking away (jump and crouch wont help, she still take damage evenknow the skull did not hit her) and hope for the best. Another area is those red ghost and some of ambush encounter. Just clear all of the ghost before proceeding to the ambushed area would help. Lastly is few red ghost mini boss area, just keep your distance and try to memories the pattern when it is vulnerable to your stun attack. Last the final boss is the most annoying battle as it is full of bugs. Some of the attack not supposed to 1 hit kill vena would, that including hands flying around and those "noodles" that falling down from the sky. That part just try your best to avoid all attack and hope for the best.
