Okay so that was a cute little game.
I do have criticism if that's allowed?
Well first of, pretty much everything you wrote in the "Notes". All of that is very bad. Though since this is a jam game, mistakes were bound to happen. Though fixing them shouldn't take too long (The misplacement one specifically).
I did manage to beat the game by having one checkpoint far to the right, getting the dash ability in one go, die, and re spawning to the right which allowed me to beat the boss (Which was very easy btw)
Other criticism. The damage feedback is near non-existant. Whenever you or an enemy takes damage is never really sure. I can propose many solutions for that but i'll only propose them if you're interested in updating the game.
Another problem is a sheer lack of story. To me, your lore was inspired by darksouls. But in darksouls, you are always reminded that you are special. But there's no dialogue in Wickborne which disallows this. The boss doesn't fit in the story does it? To me i just got to a random dude's home, stole his gems, get into his room, and beat the shit out of him. Like. How did that help restore the flame??? Even something vague like making the boss ignite when it dies or SOMETHING, ANYTHING. (Damn i sounded salty here XD. Don't worry i ain't mad or anything. I just see a lot of potential here.)
could i know the time it took to make the game?
Overall a 6/10 game. Cute graphics. A story (Though unexplored much). Tough platforming (In due part to the sheer amount of horizontal momentum of your character, which makes precise jumps very hard.). A nice metroidvania with a nice fluid progression.
I can see that you had some playtesting. Well i assume you did based on the portals made to make getting out easier.
