For the record, you get more replies on your level thread than the average guy walking the streets with a level. Like, people would whistle Teenage Dream out their nose for the scant coverage you get. Maybe instead of giving up, you get better. Like, imagine if Volcove were to throw in the towel after getting shafted in the 2nd LDC. That'd kinda suck, wouldn't it?
So my advice- get your ♥♥♥♥ together, get better. Here's a great start- the levels
here and
here are the best the site has to offer, hands down. They've inspired many a potential LDer (like SMIC) and created careers. Brilliance begets brilliance, after all.
Trust me- don't get discouraged when feedback isn't great. Rome wasn't built in a day, and even the earliest medal winners were, with some exception, just beginners, as was everyone at one point. You've got the dedication, you'll do fine, so long as you don't give up.
(and for the record, I can't actually play your levels right now. I may in the future, but hold no promises.)
