Hey, pretty neat (and hard) game! A few tips:
1. Maybe use different music next time.
2. The death sound gives me a heart attack everytime i hear it.
3. Sometimes you die immediately because your cursor is where something red is.
4. When you touch the red thing multiple times, you can hear the death sound several times. I don´t know if you want it like that, but a simple fix would be to have a bool called "hasDied" or something that is set to false. You only play the death sound if it´s false and when the death sound has played you can set it to true.
5. Use a diferent backgroundcolor then the standard one, just seems a bit more proffesional. :)
6. Nice drawings and animations.
Hope that helped you a bit, if you want to you could give me some feedback on my submission.
