Interesting game. It seems like you have to be moving + click interact on ladders to use them and that seemed weird. Enemies could be more active it's understandable - you didn't have much time. I liked how sounds changed on every floor - nicely done. Your character controller could be simplified(was acceleration intended?) by having static move speed and changing velocity to 0 with OnCollisionEnter2D(). Also, to make character stop and turn faster - just increase Rigidbody2D linear drag in inspector :). Graphics look nice, thou could be a bit darker. Overall, pretty nice game, considering how little time you got. Good job!
