This game is very ice cream. I highly recommend working on your cover and game page, those are holding it back significantly. Extremely fun. The art is creative, the idea is so good.
You can go a long way using itch's default template. Just set up the colors, font, add screenshots, maybe a banner etc and you are good to go. That is exactly what I did and I am pretty happy with how my game page looks. For the cover. You will need to put in some effort.
