“It's very cute but unfortunately a bit too clunky for me in terms of basic moving mechanics. I think if I was more patient, I'd have given the game anothe chance.”

“My score: 6/10 Overview I see what the developers are trying to do here. The game is admittedly beautiful and quite charming (though I suspect many of the assets come straight from an asset store). That said, I’d humbly suggest focusing more on style rather than photorealism,…”
