A hermit caterpillar?
The controls are a bit awkward, but that's alright. Using the shells both for protection and as a weapon is a bit complex and I don't really have a better solution at this point.
The artwork an music are really lovely, and as far as I can see everything functions as it should. It's actually pretty rare that we see such an original idea here on NG, so you can have all five of my stars today.
