Art in general, and animations in particular, are impressive. Way over the quality expected for a week-long jam.
Control feels quite hard. Maybe it's my computer, but I was experiencing some serious performance issues when running it on the browser that didn't allow for fine movement.
Music is a perfect match. I also appreciate that there's different themes for normal play, death event and death world. Even the dissonant melody made me feel at ease in the dead world!
In short, very impressive visually, but quite buggy in gameplay.
