Thank you so much for all of the comments and great feedback!
We are very interested in that sequence break you mentioned. I think I know what you mean by damage boost. Do you happen to have or do you think you could do a short video or gif of that part?
If not, we understand and can probably find and/or recreate it.
Thanks again!
Here's a video of both the damage boost and some wall climbing you can do with the grapple. The wall climbing is not easy and pretty tedious so it's more a cool trick than anything problematic. You need some horizontal space to climb, so if you fall in the narrow pit next to the upgrade you're softlocked (unless you have the climbing upgrade of course). It's possible to climb up to the ceiling of every level and reach lots of places.
