Wow! This is a really simple yet fun game! I love your take on the theme, and the addition of the chromatic aberration makes the impact just a little more impactful. The idea that currency is also health is also a really fun mechanic that i'd love to see explored in other games. Overall, for your first full game at 14, this is really good! Getting into game dev that early is always a good thing (I've been doing it since before I was 14 too lmao)
Great job!
