I had similar issues where at the 3rd stage, my character couldn't move even after selecting cards and then getting eaten alive by crabs. The menu didn't work very well for me either, where when I clicked on it, it wouldn't take me where I wanted to be.
I did really like the game and the mechanic behind getting the ice cream, I just wished I was able to progress more into it. The SFX of the crabs scuttling I thought was really amusing and I enjoyed the music a lot. It had a nice whimsy that I enjoyed that felt very retro. The art was charming, it felt to me like it paired well with the music.
A few suggestions for art-wise is that I wish there was more texture or indication of sand, and the cards would read better with more visual elements in it. The character itself also could benefit by some slight dark lines so that the silhouette stands out better instead of his skin tone and slippers blending in with the sand!
This was fun, I do like some card games. ☃️☃️
