How many mechanics do you want? Yes. Impressive for adding all those mechanics in such a short time.
My thoughts:
I felt a bit overwhelmed, so when I got the the last door i was happy. I think I missed something on the way there, could not get up to the door, even if i had one small box i could bounce on. Tried dashing and double jumpinging without any luck either. Had no way of backtracking to understand what I did wrong.
