Thanks for the feedback! The chest issue was a bug, due to time I just have it now removing the chest completely to avoid confusion. I've added more rocks to that puddle too. Not sure why it was not appearing at first.
I lowered the snowman wall thing to only 2 hits. I agree it's a little tedious haha.
I also fixed the message from that first guy. It should always give you that hint that you missed.
Thanks for the credit info! I fixed that timer too.
