I like the spritework and music.
I think you should look into what makes a good jump. A platformer game really needs good controls.
I found that you can also go through the dialogue by pressing WASD, but this doesn't actually advance the cutscene, so when you reach the end, you have to press E a bunch of times to catch up. The first time, I thought I had softlocked the game and refreshed the page.
I didn't like the timing minigame. I think you should give the player more feedback, because I didn't really get what I was doing wrong. I also found that trying it again after failing once completely broke the minigame giving me a free pass.
The font was kind of hard to read.
I liked the story. Plot tends to be low priority in short jams like this, so it's nice to see.
