Hi Kenney, Beat Em Up templates; more Space Ship side options; rivals, like aliens for Space Ship side.
I use the MATE version.
After I wrote the original message, I install wine and run the Kenney Studio.exe. It works, and looks great.
Great that you do a version for Gnu/Linux!
But It's not working on Linux Mint 17.3 :S. I try install the .deb but it returns a 100 error code.
I will try use Wine with the Windows version.
