Wicce - Playthrough Part 1

Started playing Wicce - a 2D platformer where you play as a witch trying to find her daughter (I think). You have a basic combo attack with the broom and a charge one shooting out a spell. There are a lot of mobility options like double jumping, sliding and air dashing. Wicce can also heal herself with herbs she finds in the levels, but you die immediately if you fall in a pit. I beat the first boss and the levels seem to get more complicated, but I'm not sure how and where you can save your progress. Another weird thing I noticed is that you can't go back to the previous room so if you missed some collectable there's no way of getting it.
