Love this! super satisfying movement and I thoroughly enjoyed the ramping challenge up to the overhang section right before the summit. One improvement I'd like to see is that it currently takes two clicks to picking up ice pick and then re-insert it into a new block if its already on a different block, which led to a lot of frantic double clicking when I was trying to quickly climb. Consider just making it one click to both remove and reinsert your ice pick if you have a valid target? that might make the controls even more satisfying. I had a lot of fun climbing to the top of the mountain and I think you did a great job!
