I wonder how many people saw the readme file?
Also, one or two of the Last Words were okay, but the concept behind way too many of the attacks overall involved putting a laser in your face and/or directly under the boss and/or spawning bullets rather close to you. Hitboxes don't seem to be quite as precise as one would hope for the kind of micrododging you have to do at times. Where present, backgrounds weren't bad. Sonja's nonspells weren't horrible from what I recall. I think I recognize the name Ylle from someplace. Attack power seemed rather weak for Suika and Alice, and their bombs weren't great.
It needs polish, but I think that's the point.
