Fun game. I got to the end, although I feel like cheesed a bit (I just went through the wall that was guarding the flower, not sure if there was a trigger on the right side).
Some deaths felt a bit cheap... nothing major but, for example, on some platforming sections you have spikes in the bottom that you can't see immediatly, while in others you have enemies. Also, I'm not really a fan of being able to be soft-locked, but I don't have any good suggestions on how to fix that...
Other than that, it felt like a really solid entry.
