okay i have a partial solution, if you download the latest windows version, then replace the contents of AppData\LocalLow\Netal\Turnstone Falls\save_1.json with
{"version":1,"position":{"scene":"Pillar","terrainRotation":237.52645874023438,"zPosition":-31.79437255859375,"yPosition":0.286250591278076},"storyProgress":{"hasArtefact":true,"hasDoubleJump":false,"sheepCollected":[false,false,false,false]},"flagDatas":[{"file":"player","flags":[{"name":"has_artefact","data":"1"},{"name":"has_double_jump","data":"0"},{"name":"befriended_count","data":"0"}]}]}
then the game will load as if you had touched the water and it hadnt softlocked
