At long last, I've finished. Here's some last-minute comments from the end game.
"...chisel, breaks..." should be "...chisel breaks...".
"...grubs put in cage!" should be "...grubs, put in cage."
There are about seven rooms with glowing grubs, but you can only drop the moss in one of those rooms for the grubs to eat it. That's pretty mean. If it doesn't work in the first room you try, why would you expect it to work in any of the others? It should work in all grub rooms.
Moving west from the submerged passage was pretty mean. I had tried a dozen different ways of swimming, diving and entering the water, but SWIM PASSAGE? Give me a break. You don't swim in a passage, you swim in the water that is blocking the passage. You really need to allow for some alternatives here. If the player's intent is clear, then allow it.
Why is it that you can SWIM PASSAGE from the sloping passage, but you can't SWIM LAGOON from the craggy rocks? They should both take you to the same place, but the latter says, "No way! It's too cold now, brrrr." Are you going to try and tell me that the water is a different temperature depending on which direction you approach it from? You need to be consistent here, or remove the exit to the west of the submerged cave.
"I can't walk in those directions!" should be "I can't walk in that direction."
"...clasped around it's head!!" should be "...clasped around its head.", i.e pronoun, not contraction of "it is".
Boy, this is one hard game. I enjoyed it, but it sure is cruel. I doubt there's too many people out there that would have as much persistance as I have. Good luck with the enhanced post-jam version. I'm really looking forward to those graphics. I just hope that it's a bit fairer.
