I'm scared of bumping this topic but I'd really like to voice my opinion.
This mod is brilliant. I mostly have no idea which enemy replaces which. The graphics are even more amazing than DitD and the atmosphere is incredible. The only place I didn't like much was Altaire Prime but that's just a matter of taste.
I LOVED Frosthool. The level design there was brilliant. I've been unsuccessfully trying to replicate Jotundra Mountains in Botafloria because it's exactly the kind of environment and difficulty I'm aiming for.
Fort Yetisburg is a neat pun
I liked the music but the actual level was a bit confusing. Still not bad though. After playing it I started to kind of like the frosty theme.
Then there were the Jotundra Mountains. Pretty cool, nice jumping, slopes everywhere and good use of Yetis. It really felt like a cold and unwelcoming place. I thought that this was pretty cool.
Then came the Frosthool Station. My jaw dropped.
This was by far my favorite level in the entire game. The detailed environment, the stunning windows with a beautiful sight of the mountains. And the music. I last played the game 3 months ago but I still regularly catch myself humming the Frosthool Station song. Is there an original MP3 version anywhere?
I loved all the clever puzzles in this level. It felt like a completely different game, but still incredibly keenish. The music helped the atmosphere a lot, made the entire level feel barren but at the same time incredibly fun to explore. Like I really was on a far away icy planet needing to find something important.
Of course this wasn't the only level I liked. You did a great job maintaining the Keen 7 feel in the Krodacian Overlabs. The dark, creepy songs were very similar to the ones in TKoK yet much more pleasant to listen to. I liked those levels too.
The secret level was awesome, especially the beginning.
The second-to-last level had awesome music and I liked it. Just like the first level.
And the boss level... I figured that a well patched boss fight would have something like this one, but I had absolutely no idea you could do THIS with the QED tiles. Insane job, Levellass. The actual fight was pretty hard too. And when I was done, there was still the ending with that great song which really made me shed a tear.
Thank you for making this mod, please don't ever change Frosthool. Ever.
