Nice little highscore game. For a simple clicker game, it’s very satisfying. I liked the art and audio the shader fits it well. I found that I could abuse the game a bit simply by spamming Z, as there is no punishment for doing so :) Additionally, I would have liked to see a bit more visual indication that a window is going to time out soon (would be funny if it went non-responding the last half-second, but I don’t know if that would be good design). I would have also liked to see a bit more punch to losing a heart, like screenshake. Excellent entry!
