Wow, this is looking FANTASTIC! I haven't played through since most of the new changes have been made. This post has been a stream of reactions which I am now trying to clean up.
1) The changes to the lab 4 region, the AMAZING notes, and how it ties in why their is a guy just sitting at the lab 4 entrance are fantastic. BUT, how do you get back out??? I walked in there right after getting the climb power up but that is not enough to get me back out. There is a switch, but it doesn't work. I'm using KS+... could that be the reason? (Edit: Bah, never mind, just a tricky jump.)
2) There is still no place for the umbrella and we have even more locations to use it. I personally would like to see it show up before we happen on lab 3, because of the two updrafts there, but would that create problems with the core challenge course? So far, all the things the updrafts lead to are just bonus secrets, so I suppose either 1, it could show up later and if you really want the bonus material you can go find it out, but that would be a lot of back tracking, or 2 we can give it at some other point and perhaps even make one of the updrafts a required step in the game. And by the way, the updraft leading to the hot springs if very cool. I wish there was something more happening up there than just a cool location. Anyway, I was thinking the guy in the attic in the village, perhaps there could be a way to get up to him and he could give you an umbrella. Don't know why he would, but it just seemed like a good way to solve the umbrella problem.
3) I'm not positive I like the way the lab 1 entrance works. First, because it is a dead end right now (that screwed up my save file, but I have sense learned to edit the save.ini files thank goodness), and secondly, I really liked how you use to go up into that last whole of light in the last background screen like you were emerging up into a dry lab (though it led to the sky for some bizarre reason at the time). I dunno, this is just personal picky-ness, but I thought I would bring it up.
4) I got very confused once I got into lab 4. There is the beginnings of a local history, but it is blank and there seems no other hint to lead the player back to lab 2. Are there plans to help that out, or did I miss a hint?
5) So, I just figure out the scenic rout to receive card 2 (I think that is the card... the one that is in the reactor). Nice job! I like how it ties in to the flooded lab 1, though I don't think it you can get to the other side of this room from lab 1, which would be cool. I would suggest that cracked glass would not be the clue and the way into the sign room, but a port whole tile. As for a hint that there is an easy route, how about a note somewhere that mentions an emergency cooling shaft located right before the reactor area? I would just like to see something that clues a new player in to the reality of an easy path, because I didn't even know it was there my first time through. I might have found it if it was my first time through, but I'm very unsure of that.
6) I keep noticing a flaw in the snow animation where it creates a white line across the screen. This happens anywhere it overlays with a white back ground.
7) What if we at least tried to tie the linear green fire road (was that the name?) in with the rest of the game by having it at least mentioned somewhere. Something like: "There is a strange ancient device in the ice caverns that claims to lead to the future. Whatever that place is, there is an annoying person there who wants to race. I'd just stay away from him unless you have to go there for research purposes. He really gets under my skin."
So, in spite of my criticisms, this is looking SO fantastic! I LOVE all the changes! This level is turning out so fantastic. And call me completely neardy, but it is REALLY exciting to finally get in to Dr. Wood's lab! :D
So this next bit of spoilers is just all the random crud I was writing before I had a complete picture of all the new edits. Read only if your very board. Old edits:
Edit: where is the old friend's house? prob with knytt+
...and I've been in the reactor for 30 minutes... isn't there suppose to be an easy path? Did I miss it or has that not been done yet?
Edit again: So I hope this isn't annoying. I was thinking the game was playable now, but after FINALLY getting through the reactor (I never want to do that again so long as I live) I can't figure out the step after lab 4. There is the beginnings of a local history, but it is blank. Ok, got it, back to lab 2. But there doesn't seem to be any hint to go back to lab 2. Could we get one?
to take a turn with some of the improvements I mentioned.
