Good job on the effort you put into this!
For feedback, try to avoid mixing too many assets that don’t match. it can give the game a “low effort” vibe even if the idea is good. I also appreciate the voice acting, but be mindful of the player experience: some people just want to play and may not care about the story, so adding a skip option would help a lot.
And for a platformer, checkpoints are really important. Going back to stage 1 after dying in stage 2 feels too punishing and makes the game harder than it needs to be.
Overall, solid effort keep improving!
