Nice implementation! I appreciated the title screen with the information on playing, it really helps to understand what comes next. I also thought the visual design of the sprites showed their function clearly, i.e. if they were dangerous or beneficial to the player.

I did miss some good sounds as feedback  to getting hit but I feel the version of the game and controls as implemented allowed me to enjoy the experience.

Good job!

Tight controls, I only died when it was my fault. Nice job!
