Hey! just checked out the stream of you playing! we are really glad you liked it! first off, you got super unlucky with artefacts... theyre a 1 in 5 drop chance but u seemed to just never get them which was unfortunate. Also yes the game uses a raycast line of sight mechanic to break blocks and when the silver or other blocks were taking ages to mine its because u shouldnt have been able to reach them thats a bug we didnt find ourselves. other than that we are glad to hear you enjoyed the game and was super fun watching you play it as a first reaction stream! love the stuff keep it up and ill check out your game and streams too! =D
