the gap between hard and insane is too big...the insane feels like an extra, it's full of unnecessary jumps, but even if you feel like the jumps are necessary, there should have been a difficulty between hard and insane 3,5 --> 4,81 is really intense...hard is too easy for me for example but insane is too hard...there are way too many jumps and it is really frustrating, I'm just saying this that maybe next time you can take more care about the spread X_X (but individually the difficulties are nicely mapped)
