I tried out the update and got an ending where the clothes dissolved but no transformation. I wasn't expecting a third ending for just reaching that halfway point, but it is very interesting. I might try to go for an ending with the clothes intact; however, the slimes that block the maze area still feel too in the way with too many numbers and it leads to massive damage every time. The zigzag hallway at the end feels a lot more fair to me and is probably fine as is, even if I get a little bored with how slow I have to go to avoid hitting every wall. It probably also helps that I'm a returning player and understand the layout a lot better now.
Editing this to say that each minute on the timer is a full minute, so for anyone wondering you have 6 full minutes to reach the exit.
