Because, word. You're describing my own initial KS experience, exactly. There's some really annoying aliens in my favourite show, Farscape, whose sorta-catchphrase was, "Why so diffcult?!?" - that sort of became my own catchphrase in the first few months of downloading KS levels.
Thankfully, there *are* quite a few nice environmental and playground levels out there (and 'normal' difficulty challenges with nice visuals, too). Sadly, the old forum is gone, so I can't recommend you go and search it for environmental level recs anymore. But a lot of my own recs in the
'your favourite level' thread here on this forum, and most of those of the other members of the League, should fit your requirements. (I say 'most' because I do enjoy the occasional challenge, and have even completed, and liked, some 'hard' ones.)
All of my own currently published levels are either environmentals or easy to normal challenges with - I think - nice visuals, too. You can find two of them in my sig, and the third
here.
One of them, Falling Water, I am still continuing to expand; it will be a huge environmental with very minor challenge elements (if any) when it's done. This is going to take time, though - my current estimate is another six months, minimum. (I started building it in June or July last year, and it's 320 screens now.)
You may also be interested in the recent, spectacularly successful
"A Knytt in Time" by egomassive. It's currently a normal-difficulty challenge occasionally edging into 'hard' territory, but egomassive is building an additional, easy/environmental version of it (thus earning the eternal gratitude of the League of Crap Players, and this special mention *g*), which sounds as if it's going to be ready soon.
Anyway: welcome, and may your search for easy and visually pleasing levels be successful. If you find any that we haven't recced in the favourites thread yet, do rec them so we may find them, too! :-)
