Should I buy the DLC if I liked the first (and only) map? Is it worth it?

Hey guys, I've tried to play this game using Steam VR with my Quest 2, but strangely when I launch it, the game is running on my pc, there's even sound in my headset, but I'm still in the loading world, with Steam saying "Next : Adventure Climb VR". How can I resolve this?...

Can somebody help or give tips to get the following achievements Arachnophobia Ascendant Mission Top Out Super Sonic

Question to dev: Is it some kind of pre-game planning poster or whiteboard?

I have tried using both the index and side triggers together and separate for long stretches and have not gotten the achievements for grabbing rocks. They all say 50/51 or 100/101 and do not progress. I just finished the ic3 climb, which for sure has more than 50 handholds, and played the hidden canyon a bunch to get the supersonic achievement. Every other one has progressed and triggered fine, but not the basic touching rocks achievements. Any suggestions?...
