I just got done playing through the demo of Blind Forest.
It took me a while to adjust to Ori's controls as he's much quicker and less weighty than I'm used to in platformers like Mario and Donkey Kong; I overshot my jumps a lot at first. Even this early area was a decent challenge, and I did die a few times, but I felt like I was starting to get better by the end.
So the sequel used regular autosaves does it? I ask cos apparently the first game doesn't, you have to spend energy cells to create your own checkpoints.
