My name is Bartek (short for Bartłomiej, meaning "Bartholomew", though "Bart" is shorter), a Polish Mugen content creator who makes characters usually based on video games, though I also create characters that aren't from games. I released my first character in July 2022, which apparently did pretty good, which pretty much allowed me to make more characters and become more familiar with Mugen.
I also sometimes create edits out of some characters that look good but have several noticeable flaws (such as balance problems and other stuff), most of which contain various improvements from the original to give them a much better quality. I also make some patches, most of which are balance patches to make a character more enjoyable and balanced.
Outside of Mugen, I focus on Mario Forever and I do various gameplays of MF fangames that I really like, though I also focus on other games outside of Mario Forever.
