I have made levels with smbx for over a year, and about 15 of them have been completed. Most of my levels are made for the ASMBXT series.
I will be submitting some of my better levels after they have been played by raocow.
I have also participated on MAGLX and SMBX Level Contest 7.
The levels I have made are often rather short and use a lot of custom graphics. I am not good at playing hard levels. The oldest of my levels were super grainy due to me not knowing how to handle gif-files properly. I usually convert tilesets and sprites from the premade ones on the internet,
but I have also drawn some of my own. I was one of the people contributing sprites for A2MBXT.
Here are some screenshots from the levels I have made with the talkhaus version of the SMBX level editor.

There are currently no projects I am working on either.
