Can we pretend that 'Very Easy' is 'Normal' difficulty and that the real 'Normal' difficulty is, like, 'Nightmare Mode' or something? I'd feel a bit better about my gaming abilities with that switch! :D I tried it on Normal first and wasn't sure what was triggering the jumps between dimensions, then I went to Very Easy and saw that there's a timer for that version.
It still took a lot of tries and the use of the checkpoints to get through Very Easy mode, maybe I'm just bad at games! It wasn't obvious to me where the safe spaces to stand were when a dimension change was about to happen so I'd often warp outside the level or over a pit with spikes in it.
When I did know where to go, I sometimes had to wait around for the timer to count down to get into the proper dimension to proceed, so my personal preference would be to be able to control the jumps or at least be able to trigger them early. I totally understand if you wanted to keep the time constraints in, though, since it adds to the level of difficulty.
