Really looking good!
The retro art and retro gameplay seems to work pretty well for now.
Would just say that the camera stopping to move at 0:20 when you're on the left limit of the lvl made me feel weird. I don't know if it's meant to stay, but I don't like it when camera does that in platformers, it confuses me. I prefer to see the wall on the left and the camera still acting as it used to (following the player)
Also, I guess the art of the cube you move at 0:40 will change in the future? It feels weird because it's really uniform colors compared to the rest
Otherwise I love the gameplay mechanics and how it looks. Will definitly follow this
