This game was sort of a blast, and sort of a groan of slightly janky controls and deaths that didn't quite feel like my fault (even though I know they were, realistically).  Epic soundtrack, surprising platformer design for a jam, but certain parts like my character getting stopped on seemingly nothing overall caused me to stop my playthrough before I reached the end.  There was some decent design here, like I said, but a lot of the time the room design itself felt needlessly inhibited by other obstacles.  As an example, getting the F rune was actually a great feeling once I went "oohhhhhh, I know how to make that jump now!" but getting up TO that jump, I died more times on the wall spikes on the way than I did the actual jump.  I know that was sort of the idea of putting them there, but I feel in those sorts of cases the environmental dangers should have taken a backseat to the rune-figuring.  All in all, I really had fun trying to work my way through this.  Thanks for the game!
