First of all sorry for bad english.
I have noticed a few things that can be improved :
_ It would be handy that the red point for the dialogue be always in the same location to pass a dialogue already read faster. (or always have a arrow to pass it)
_ The chapter 4 is a litte buggy mainly the area after leaving the camp of wolf and before meeting the wolf girl. I've had a “enless fall” (because of the vanishing of the ground) two times before I can finish this chapter (I've got to retry twice including the chapter 3).
So it can be cool to fix it or to make a
shorcut to go directly to chapter 4 (like for the chapter 2).
_ The tutorial is wrong : A+ “down key” doesn't work to do a down attack.
Spoiler (click to show/hide):
_ The view need to be reframe. Because the ground is in the middle of the screen that makes we can't see attack or even plateforms above us like in that screenshot
Spoiler (click to show/hide):
If I jump I die because of the spikes that I can't see.
_ In chapter 5 there is a awful long time before I can inflict damage after pushin the A key. The first attack animation does not deal damage and the battles lose all the dynamism because of that. You have to wait at least 1 or 2 seconde before dealing damage.
The battle system of the other chapter, with instantaneous and continuous damage, is better (from my point of view)
Another thing, when I don't attack at the right moment (like when you hit training dummy with his thorn at the beginning) it inflict damage to me while it's only my weapon wich is in contact with it.
I aggree with Valpas about the hitbox extending when you attack that's really annoying.
(I mean when I hit a cactus with a spear I should not being hurt

)
I've got suggestion too

:
_
Add an invincibility time after suffering big damage, like quarter or half life, because you got one shot very often. (don't know if it's possible)
_ Add a portrait of captain Cuttie on the top left of the screen with detailed points of life (45/50 ect …). It would be nicer and more convenient than the current bar life.
_ Add sounds and music
_ Add different outfit depending on the life of captain cuttie (like loosing her bra ect...)
_ Why the
hearts of life of the first chapter are gone !? There was very helpful !
_ Add something that warn you you are at a checkpoint.
_
Add a restart key or button to restart at the last checkpoint (prevent endless fall or “total lock” in a part of the screen.)
_ If there is no heart of life, beating an ennemy could refill a little life.
_
Add a pause button (or a menu)_ Add something that shows it's the end of the area (screen changement are a bit brutal)
_ Add a gallery with all the sex scenes.
It's a lot but that's just idea
Otherwise that' my favorite game here. Great job !
