Cute platformer with the grem. As other people have also said, the bats are hard to see due to the lack of contrast with the background. I was getting stuck on the final part because the jump needed requires a near pixel perfect jump in order to get to the next platform. I did manage to complete it, but that jump is hard to do and the fact that you can get knocked off and have to redo that jump. I did freeze once when getting an item, but other than that, good job with the game!
