So, in reply to the last time, my computer isn't *particularly* laggy, but its an odd issue; sometimes its fine, other times I end up moving my cursor and the game is just slow to respond and move the block target accordingly. (it also lags when I try to move sometimes, nothing happens and then I move way too far for just a small *tap*) And, as for the snail shells: 1. Decorations. 2. A note block sound..? 3. Fancy swirls in builds. Sorry for commenting it here - I don't have social media. ?
