Interesting little game! The objects are a bit hard to see perhaps the background colours could be a little less saturated. Good work!
Here's my best time :D

Wow, you lost 0.217 sec at the start and still got that time. so <4.5sec is possible! And for the background. You are right but I'm no artist. For the most part I googled the things I needed and tryed to recreate it :P (Check https://glimmer5r.itch.io/can-flip-3d to see my full artistic potential.)
