Incredibly simple game, and I appreciate the concept of reaching a specific score threshold before the timer runs out as an additional goal layered onto the challenge of avoiding obstacles. I think you just need to fix up the hitboxes on the collectables, as they seem a little inconsistent, and increase the overall polish level - improve the audio beyond the simple music loop, touch up the UI, and add some more sound effects & feedback to the abilities & gem collection.
(Also, using Generative AI tools to create your itch.io cover image is against the rules of the jam, and any additional Generative AI use should be disclosed on your game's page. Consider updating the cover image and content disclosure.)
