The graphics and audio were amazing! The backgrounds really set the tone for each area and the audio really added to the immersion. While playing through the level was fun, I ended up facing several issues while playing.
I think the game could've benefitted from being shorter given the scope of the game jam. I also think that making the light attack and heavy attack more distinct could've helped. It felt like they only differed in damage dealt (and had the same starting and ending lag) and I didn't find a reason for ever wanting to use the light attack. Also, given how the player can attack mid-air, you could have added an animation for that. It felt odd to see the player jumping and making the attack sound effect with no visible change.
While I would have loved to have finished the game, I ended up not being able to go down a bunch of platforms (where there is a visual indicator to press 'S') and ended up getting stuck. It worked during my first pass but not when I was backtracking. I'm not sure if this is a bug or not.
Overall, you did a good job! I hope I can finish it someday.
