Super cool that you used Vimlark assets for the VimJam. The click to apply controls weren't intuitive to me at first, but once I figured it out I had a lot of fun working out the puzzles. I think you should be really proud of this for your first jam. It took me three attempts before I completed a jam attempt on deadline.
I know you said you wanted to scope out more jobs and other juice, but you still made a really fun experience even if it wasn't as big as you'd hoped. Great work.
