Alright, I liked the lil' crab and enjoyed the music :). The platforming wasn't particularly that fun given the limited vertical mobility of the player and the levels being more vertical. Certain powerups did give the player more vertical mobility, and I enjoyed the double jump. If the double jump was just the default I think this game would be a lot better. The tiles were also quite small, making tiny ledges and jumps frustrating when the only jump the player could do was a large jump, and the player hitbox feel large when it came to things like spikes or hazards. I do like the idea of a crab delivering packages though, and had a fair bit of fun delivering packages when I didn't have to go up or down like 5 levels to get to the delivery destination.
