I think you mean "S"? I am pretty sure I haven't put anything on "R". S is a parry move, every attack can be parried (as long as there is no red sign above your head). If you press S without pressing A or D you parry, if you press S while pressing A or D you do a grapple. When you see those blue circles you can walk up to the enemy and grapple them for big damage. Thats also how you fight the gunmen, just parry their shots back at them.
Thank you for playing the demo so far. Glad you like it!
EDIT:
For attacks you have to watch for the red star. You need to press S at the moment the red star breaks. You might want to practice on the rats at the beginning. For projectiles like bullets just press parry right before the bullet is about to hit you. Good luck! I believe in you. I also will take the feedback to heart!
UPGRADE 1.
Thank you soooo much for easy mode! Well it didn't help me kill the guy in the well and any other boss or bigger mob but I'm finally able to endure the gunman shots. I figured out how the sneaky ninja killing works (I have this on R cause I changed my controls) and I LOVE IT! It's so relaxing and pleasant, deffinitly my favorite type of killing there.
I was able to explore the map furhter and now I understand why the city has a name "City of cables". I lost myself there so many times and never know where I actually am. But when you're used to jumping it's so easy to speed run every location which I did very often. I achieve the 3th save point which is this mustache guy and now I have troubles with those two gunman on the way for the key.
And I found a bug! I recorded it so you gonna see what happen. I'm gonna explain what I did to achieve the bug:
I climb the ladder very slowly cause I didn't want gunmans notice me. When I went to this room before I notice the doors become closed when gunmans are fighting so I was checking out when It's happenin. Somehow, while still being on the ladder I got their agro but still the door was open, so I went down and there my character stuck. I couldn't do anything, I've tried every key but nothing work. So I load the game once again.
I also found another thing when you try to jump on ropes and accidentialy start to speak with the Dead Care Taker. You can't move, he is speaking and you're falling down.
It was my first time hearing sounds from the game and I must say I love it! They are so well choosen and not annoying at all! Amazing work!
Gonna try kill those gunmans, please wish me luck!
and oh I made a meme which explain my struggles. SOMEDAY YOU GONNA BE DEAD MONSTER FROM WELL I PROMISE YOU
