I thought the main mechanic was interesting. Once I figured out that each crystal gave me a power I could see that there was some thought put into the layout of the level (ex. A blue crystal next to a row of falling spikes.) I also liked the sound/glowing effect when the player got a power.

Often the player would get stuck on pixels on the ground and I would struggle to get unstuck. The spikes were also pretty difficult to see.

Sometimes my player gets stuck in the ground or on the walls, which is a bit frustrating… The idea of having temporary powers is cool. The character is strangely charming :D
