Solid game - I enjoyed this! Some tweaks to gameplay and controls could help - I didn't seem able to kill the little spider things and jumps were a little less intuitive than expected at this res - long press for higher jump makes it feel a little less responsive. I also noticed a few instances of texture bleeding (the lines between sprites) - can be a very annoying issue with Unity and pixel art games. Apparently the trick is in how you pack the sprites.
