The way the story is told here is quite interesting, there's just enough to be intriguing while still remaining vague. A lot of the more purely technical points have already been brought up by other people, but I did find that were was a bit of a lack of instruction. What exactly the flashing box around the character meant was never obvious to me.
Tutorials are hard to fit in with jam constraints, but even just having some instructions on the itch page or as a .txt file along with the game goes a long way.
Other than that, it was a solid experience, great job!
