After playing it for a while and exploring the game I think I can already write some comments on it. I agree with the people complaining about that jumping from the lower platform to the higher one. I usually enjoy these kind of jumps in platformer games, but not in this one. And to show the others why these jumps are badly designed, here is a screenshot from a level without that kind of a jump, but showing what's wrong with the character:

As you can see there is even enough space to draw a quite wide white line between the character and the platform to the left. But you still cannot jump from this point because you will hit your head with some invisible obstacle. It most likely means that the hitbox of the character is inaccurate and it is much bigger than the actual look of the guy. And this can also affect the obviously also inaccurate hit detection. Unfortunately the author did not respond to my PM about it. While this can be manageable the next thing should make the author to not only consider but rework the game. Some of the trophies are simply not obtainable. Another screenshot:

There is no way you can enter that corridor, because the character is too wide, too big. I already found 3-4 levels on which such a situation occurs. It also cannot be the exit, because - see the reason above - you would not be able to jump up from that corridor. This issue needs fixing.
Another thing: sometimes if you leave the level with the trophy, but without destroying the totem the game will mark that level as completed anyway, but not add it to the stats. On the other hand I finished several levels without getting the trophy but with destroying the totem and those weren't marked as finished. This leads to a confusing situation: if I would go for 100% completion I wouldn't know now which levels I would need to replay.
So there is some work to do with this game to make it really a masterpiece (there is a good potential for it) and to adjust several things to make the game really enjoyable, not bugged.
