I'm going to be blunt with my feedback here.
First the things you did right (In my oppinion)
- You have an options menu in case someone wants to mute the music and sounds
- Your game concept was really simple which should give you a lot of time for art and sounds
Things you might want to work on
- You should choose colours that go well together. There are a lot of websites you can use to get/make colour palettes. (https://coolors.co/ https://lospec.com/palette-list)
- The screen was zoomed in a bit too much in my oppinion which did not give me nearly enough time to react.
