This is a hidden gem, I can say that.
First of all, I enjoyed the narrative part a lot, BUT, the platforming part was a bit frustrating, and I can explain why. The player needs to be consistent with the moves, to be very responsive, that's what makes a good platformer.
Your character from the platforming part had an issue with the acceleration, because it was a bit too hard to accelerate and he stops very quickly, it needs to be the same as he starts moving.
I suggest you make the platforming part more on point, you press a button it moves immediately rather than slowly accelerating.
The art is cool, it reminds me of the game KIDS, and I appreciate all kinds of art styles.
Overall a very fun game! Keep it up!
This is my feedback.
