Thanks, it always cheers me up to hear that people enjoyed my old games! I'd like to go back to Yoink one day. The uDevGame version really is just a snippet of what I had in mind.
I don't think I'd want to do endless scrolling, but I might make the arenas wrap around so that they flow better and you don't have to keep stopping to turn around. That said, maybe there's room for a variety of level types!
