Thank you for playing Hmpf, and also for bringing this (dare I say... forgotten?) thread to my attention, since I never noticed people actually kept posting here after so many years

Absolutely beautiful level. Too many favourite areas to list, but to name a few: the blue area with green sky, the "not cursed" green/brown area, the castle ruins with the very bright green grass, the white castle(?) labyrinth, the pink and brown trees area, the "Emerald Valley" area, the white nighttime village, and the surface of the moon/alien planet. Haha, guess I did list them all(?), after all.
My first level and ...what a level !
I was touched by its beauty, motivated by the intelligence of its design, and excited by its challenge.
Thank you! Truth be told, I actually did not aim to make the atmosphere and visuals the main focus of this project when I first started it. It's something that just... kinda happened as I kept making progress on it, with me going back to playtest areas I had already "finished" drafting and then suddenly thinking stuff like
"Hey, I bet that CO/tileset/thingy I made ages ago would look neat here!"... over and over again, in some sort of iterative process.
I also really appreciate that the difficulty for the most part really did stick to the Normal, though in the red lava area I do think a couple of things were Hard or even Very Hard, instead. Those few jumps took me... a while.
Perhaps due to my intention of making each area more focused on one of KS's main level genres (challenge, maze, environmental...), I ended up going a bit overboard in those more challenge-based sections... definitely over the originally intended "Normal" skill level. It doesn't help that, after playing the game for so long, the barrier between
Normal and
Hard often becomes a blur for me. Plus, sometimes you get lucky while playtesting your own challenge, beat it on your first/second try multiple times and think
"Cool, this must be 'Normal' then"... and then you come back after a few months/years for whatever reason, fail miserably 20 times in a row and immediately think
"What the !$&% was I thinking with this lunacy here". Still, I'm glad this wasn't frustrating enough for you to give up on the game!
If you reached the art gallery behind the rainbow lock, you can consider the main level complete. Seeing that you also found the optional "Emerald Valley", the only bits you may be have missed are any of the 4 easter egg mini-areas.
The KS+ collectibles are merely extras and do not open up more areas. The coins only unlock an extra congratulatory message, and getting all 50 GCs does require beating several "Hard" challenges.
I really had a blast with this level and it helped me keeping my mind busy during some bad days. It is my kind of level, full of exploration, collectibles, with a constant sense of discovery and beautiful landscapes. Big thank you to Vegetal Gibber for this wonderful level and all the collaborators and to egomassive for all the features that brings the Plus mod. The music is also amazing!
Glad you enjoyed it man, and I hope those bad days you mentioned are just a thing of the past now. I will not go into details here, but it just so happens that working on this project (particularly during its final stages) played a part in keeping me going through what might had very well been the darkest days of my life, and this is no hyperbole. So, if this level also helped you, if ever so slightly, to pull through a rough patch... then I could not be more glad that I decided to carry on and finish it.
As I'm so spectacularly late with my reply, I *highly* doubt this is of any interest to you at this point... but if you're still curious about reaching those spots you mentioned, I'd recommend watching DonDoli's, kilicool64's or PigeonVoyageur's 100% playthrough videos on YT to see how they handled those sections, as a picture is usually worth a thousand words.

Neato!
Man, I should have played this a long time ago. I guess I've been a bit aloof from things here for a while.

I think you made great use of my music here, as well as certain pieces of extraneous graphics. Your tilesets are and always have been on another level, and yet they still feel just at home in KS.
Well, my reply now arrives more than a year later, so I'm in no position to complain here, am I?

Glad you enjoyed the experience and, of course, glad I could do your music justice here

It really is no exaggeration to say that the level would not have been the same without it, as the very design of some of its areas came from me listening to your tracks while trying to draft in the editor something that would fit the mood.
