This is an absolutely phenomenal game, the levels of rage I felt were just on the brink of manageable so you've struck a great balance! The only issue I found was that the frame rate dipped quite a bit in the later levels when things started getting more hectic, it wasn't a gamebreaker though, just a slight annoyance.
Just wanted to add, did you know that this game leads into https://fredbird.itch.io/heavenly-escape <-this game? With the sword following and the little friend at the end. Its a not-so-sequel-sequel.
Yknow. If you wanted to make another Lets Play xD
But I guess this is an older bad version, and is being updated soon, so maybe wait for the update before you play.
