I wasn't able to play long because I kept running into that bug you mentioned where it freezes. But here is what I found. Very interesting concept with the characters having different stories that you choose from! I love this concept, however in each of the events where I chose a character, there was a game breaking bug that froze me in my place. After the game jam, i'd love to try this out again when this is fixed. Overall from what I saw, I like the designs of the characters and the music was very pretty! I also love the weather FX and lighting to the forest map but the indoor map where I played as the blue knight needs a little work. Big empty room felt kinda boring with just 2 statues. I also love that you explained the reason as to why the player morphs into one of the chosen characters.
Great job and good luck :D
