Great script, has a few issues, however.
1. Slow and relies on auto retaliate to attack and kill crabs.
2. Limited to one spot and doesn't often move to attack crabs in other areas of the map, also limited to west crabs.
3. Literally useless on populated worlds, doesn't attack any other crab besides the ones that started attacking it first, crabs can be stolen as well because of problem number 1.
Aside from these issues I really haven't had any other problems with the bot. The banking and walking features are literally flawless and incredible and on low population worlds this bot actually does more than half decent. Expect at least a third less experience using this bot when the crabs are crowded.
