I only changed the first area, and didn't fix any of the bosses. One of the 'gore demons' spawns inside the wall, so it glitches around. Other than that, the pathfinding works pretty well.
Some bugs I found: Clicking the screen while pressing a key during the tutorial advances the text by 2 costumes, skipping a line of dialogue. You can click both the computer and mobile buttons if you are fast enough. Doing this allows the player to move at double speed.
