It's cool that you included multiple endings; it adds replayability. People like me, when we see a counter like "1/5," want to collect every last one before quitting. The design is very simple—you can tell not much went into the level design, so the game looks a bit unfinished. But that’s the nature of a game jam: you do whatever it takes to finish by the deadline. It’s excellent for a first project! Keep it up!
