At this point, my group has reached the conclusion that traps fall a little flat compared to the first game. I think part of this comes from the fact that dashing is often the best strategy for tackling the challenge. Just dash over one patch of damage rather than puzzle out how to properly solve the room.
My suggestion would be adding a clear suppression of the dash mechanic in some of the rooms. The more methodical solving of trap rooms was often more fun in the first game in my opinion. That being said, it doesn't need to be all the rooms. In fact, some of my favorite traps from this game have been the ones that expect the utilization of the dash mechanic. I think a variety of traps that allow/expect you to use dash and traps that force you to move at a normal speed and time your movement would be a nice change. I think that opens up some more creative room for traps as well given dashing can invalidate a large section of the room in a very quick manner.
