I was really impressed by the presentation here! The environment design, use of light and particle effects, sound and music, and the voiceover all feel nice and polished for the jam timeframe. I thought the main music that played while fighting the wraiths felt somewhat at odds with the tone expressed by the narration and visual style, but I did like it a lot. Everything else was well-balanced, distinct, and nice to look at; I especially liked how the design of each level felt meaningfully different without using a ton of different assets.
I think the style here is strong enough that you could expand this into a much larger game if you wanted to. The vibes are on point; greater use of enemy types, abilities, and incorporating the environment more could make this a fun and even moving experience if the story was extended. Nice work!
