I liked the aesthetic and design of the main character. It's unique and unexpected, and the graphics are nice and visually pleasing. It's a little different from the "norm" of this jam but I really liked it. The sound effects made from broken glass also worked very well.
The gameplay just didn't do it for me at all, though. I found it incredibly confusing and very tedious. The explanations on the game page didn't match what was happening on screen. The only thing that seemed to work was hammering U, which does damage but takes forever to kill enemies (and sometimes seems to fail for some reason). I was also able to sometimes dash with O, but I didn't find it useful. The red bar I understood as health, the blue as stamina, but I still don't know what the orange bar or the bar above my character really mean. The unusual controls were also a little awkward at first but I did get used to them.
I totally understand starting out with a very different, much bigger concept and having to rework and cut it down partway through, though.
