First of all it was fun to test this even i am not much into rouge-linke games. But i played tons of hack and slash games. So i am not really the target audience.
I know having feedback always help (no matter if good or bad, i hope you share this thinking), this is why i just want to provide some feedback i noticed while playing that might help you.
The theme while fighting is great, it reminds me at doom themes.
Having destructables in the environemt is perfect, so a lovely addition to the game.
Fighting itself feels mostly good.
Just this lock into animations does not feels really good. I guess this is meant to be this way, i am just not a fan of this in games they do this.
It is hard to see the spike traps as they use the same colors as the ground itself.
I would make it more stand out a little. Otherwise you cant enjoy watching the environment because you always search traps at the ground.
And it is really hard to jump over this spikes without getting hit. I tested this standing there and just jumping over and over again 
.
I guess it was not intendet to simply walk at the wall to not getting hitted.
The way the sword at the back moves if you walk looks a little strange. I would use a fixed socket for this that not move as much.
Camera movement seems good but this movement also somehow doesnt feels right to me for such a game.
Maybe give an option to hard lock the camera behind the player?
The automap loooks good but i miss an clear indicator where i have already collected something or have been.
I guess giving the doors i already walked just simply another color would help alot.
Hope this helps.
