I liked how you implemented the theme and the squishy animation of the crawling felt satisfying. I like how you had to combine different abilities together to advance - this extra complexity could definitely make for some amazing new levels if you decide to put more time into this. My main criticism would be that the game was a little confusing at times about where to go and the lack of sound made it feel somewhat dull sometimes.
Overall, this was a good game and I enjoyed playing it.
