Congrats on completing the jam! I think you did a great job at the theme. A short tutorial or description that dying in a specific way granted you a specific power would be a great addition.
It was our very first Jam and we are quite happy with the result.
Yeah, we intentionally let the core mechanic be part of the puzzle to make it a little bit challenging since we didn't have time to do a lot of levels. But we will definitely make it more explicit as we add more content.
