I joined a server, and there was someone on it, (he played Blockland). He told me his username and I recognized it, He was swinging everywhere on buildings near the spawn while I ran round getting killed by monsters (I freaked out the first time I died as the scream when you die made me jump). We then worked as a team to complete the first level (To he honest, he did most of it). Then he lead me to the grapple hook, and he taught me how to swing effectively, then taught me some code you needed to input into the console in order to be able to buy things, and that's all I really remember.
