Well, I won't talk about the problem with the camera, you already know about it. However, there are many other problems that spoil the impression of the game. First of all the coyote time technique is very useful for platformers. Probably a third of my deaths in this game was due to the lack of this.
The second thing is that all the actions of the character are very sharp. Character go up very fast after pressing jump button and then it flies down like a stone. You should smooth that behaviour. To achieve this, you need to work with the effect of gravity on the character. For example, you can reduce gravity while the character is at the peak of takeoff. This will give a much more responsive flight control and, as a result, a pleasant feeling for the player. Gravity during the jump and fall should not be equal. You need to choose the values so that the sensations are the best.
Thirdly character behaviour sometimes is very unstable this is especially true for jumping on walls. Sometimes I can jump straight up the wall and sometimes can't. Sometimes I can slide through the corners sometimes can't.
4) Level design is basically cool. I like that you can see the whole level at once and this is apparently along with the bonfires a reference to dark souls. There are only 2 things I didn't like:
a) On the left door level all floors are about the same. Yes, each floor is a little more complicated than the previous one, but considering that I spent about 30 attempts to complete each of them, this does not save them. I would like a little more variety.
b) I really need a bonfire after the destroyed bridge on the right level!!!!!!!
5) On the left level there are some performance problems when you are on a rotating platform before green swinging bridge(bridge is really cool, ьy hands were shaking every time I passed it). Maybe it's connected to camera issue but I reallu don't know.
6) I didn't pass the game. I have died probably more times than in the entire passage of dark souls 3.
About 2 hundred times but the second broken bridge together with the first broken bridge broke me. However I completed left level and even walked across something like a roof to the royal throne with a skeleton and two locked chests.
To be honest, I think that the problem with the camera is serious enough for you to use the right to reload build after the time. Since in the current state, I believe that the game cannot be passed by anyone who evaluates this game.
Please don't think that I want to offend you in any way when I wrote mainly about the problems of the game. I just think that the main task of jam is to test your skills and improve them thanks to feedback from other people. To make the games better in the future. And making games is really difficult. Second-class hero was developed by a team of 6 people, 2 more periodically helped us. And neither of them had a wedding in November. And as far as I understand, you worked alone. And to make a full-fledged 3-d platformer alone in a month, albeit a buggy one, in the month of the wedding... Not everyone is capable of this. So in any case, you can be proud of the work done.
P.S. I wish you a happy married life!!!
