I really like this rendition, and yes, this *seems* to me to be better looking than the original thing!

Also had no idea about charpad, only tried project one so far (and it's kinda clunky and buggy), so I'll definitely give this one a try!

Wow. I'll probably be burned at the stake for this but this looks better than the original. Thanks for sharing.

Woah, that koopa is perfect!

and I understand why it's blue; because the greens in the palette aren't dark enough ;)

Okay, minor errors fixed - some weird rendering issue on exporting the tile map, that I hadn't noticed - thanks for spotting this.

I like it! It's certainly different from my take.

However, some parts are not widepixels, namely the vertical lines on the middle brick block, the curve on the top of the hill on the left, and the right edge of the pipe. The screen also cuts off in the middle of a widepixel. It's a decent piece, but has has a few small, easily-fixed errors.

Also, out of personal taste, I think the koopa should be green instead of blue. The only blue koopas I can remember were in Super Mario World. 

Thank you for your time.
