Yeah I think you covered everything, appreciate the explanations. I think autosave is fine as a default but would appreciate a setting to turn it off.
For glitch #5, I completed the tutorial from a fresh install, went to main menu, turned off the setting, overwrote all saves, and reloaded. Setting is back on.
For UI #7, it was fixed after restarting the game. If you enter R-1, beat the level, and enter it again, the enemies spawn further and further to the right each time. It takes longer for them to jostle into position. Easiest way to see is to enter R-1, run away, rinse and repeat. It doesn't seem to be an issue on other levels.
Overall, I think the enemy positions could be clarified. Maybe shift the summons further to the left and organize the enemies into columns. For example, in R-1 you could have 4 columns of 3 wolves.
For the overall mechanics, I think you did a great job. Hence the comparisons to Dark Souls.
