About the HappyDiggers RPG mod pack

[CrouchingOcelot]

Please dont get rid of smart moving unless it causes stability problems. It takes some getting used to, but the climb, boost jump and crawl abilities are useful once you get used to the controls for them. I've used [ctrl] to do ledge grabs on jumps that I could not normally make (like long gaps or high hills) and have broken into mage towers and houses by crawling through gaps in the walls.

Also you mentioned removing playerAPI. Some mods depend on player API and removing it will prevent some mods from being added to the pack. What's wrong with player API?
