Interesting entry! Here are my complete feedback:
* Positive points
- Great art style, simple but efficient + I like the color scheme
- The concept is quite fun
- Nice global sound design
----
* Negative points
- The movements of the character are imprecise, indeed, it goes too fast on side movements
- The colliders are not precise too, in fact in 3rd level (I think), I got hit by the pikes, whereas I was well behind them, so it seems that the collider was too big for this element
=> Overall good job!
