Glad you liked it! I put in a lot more effort than I'd expected to at the beginning of the jam, that's for sure. I figured I'd maybe use half the time alotted... that presumption didn't hold long.
Game of Thrones is a huge influence despite my complex love-hate relationship with it, as I've mentioned in my postmortem. The Witcher wasn't a conscious influence, but I have some familiarity with the verse and I've played a bit of The Witcher 3: Wild Hunt and I can see where you're coming from there.
Which castle entry scene are you talking about? I started out with the intention of making a serious game but in the end couldn't resist having fun with it.
One of my friends who tried it mentioned the floaty movement. Unfortunately this was I think 2 days before the deadline so there wasn't much I could do about it at that point. There's also some bugginess with non-terrain surfaces (like roofs) which probably doesn't help either. Movement needs to be fixed in my main project as well, it has a similar floatiness to it although it's not as glaring since that one doesn't require you to do parkour. So that's definitely something I'd like to improve in the future.
I found myself using power attack almost exclusively in testing, usually in combination with power dash. It definitely is a lot more satisfying to use than the normal attack! I did increase the range and rate of the normal attack after some testing which made it a little less useless, but still boring. So swapping it out with something more effective (and maybe more magical?) might be in the cards if I take this further.
