Art is really good! I really like the environment and the character design. Specially for the main character.
Gameplay wise is also really good, the controls are smooth, the jump and slide don't clash with each other, the enemies attack as their design imply and the hitboxes are well placed.
I really liked the idea of being able to stand on enemies, it'd be neat if you could get on top of the one that rushes while it's moving.
Sadly I can't say much about the music because at least on browser mode it doesn't play any, so I can't comment much about that. EDIT: I just notice that it had music, I just had it too low to listen to it... Now I can say that I really like it!
As for feedback, I'd suggest moving the character behind the middle of the camera when moving in a direction to be able see what's going ahead. Currently, the character seems to go ahead of the camera so it's difficult to see.
Despite it being cut short, I still had fun playing what this game had to offer :3
