Hi! Played a few rounds in the browser — honest impressions:
1. First minute: everything was clear right away. It's a familiar merge formula, so I didn't need a tutorial to get going.
2. Sound, UI and game over: they felt fine to me — nothing broke, nothing confused me.
3. Is it "just another merge clone"? Honestly, no. The art style is really nice and gives it its own personality, and the SHAKE feature is an interesting twist that I haven't seen in other merge games. Those two things make it stand out.
So from a player's side I don't see an obvious "quality" problem — maybe it's more about how quickly the reviewers could see what's unique. Showing the SHAKE mechanic and the art in the first seconds (and in the cover/screenshots) might help. Good luck with the next submission!
