many, its also a try, old idea passcode+cheatbooks to switch by parameter in url in best case, saving time of loading and resources, clear there are also addressables, but for 2 diffrent itch url have not seen yet,
its same game just other url level starts at the beginning, music changes, to fix sound of level 2 music, it have been splited in 2, we found settings to fix for level 2, but it was also a good try to see the play and switch of players from level 1 to level 2 (just for info unity has changed the way of url?parameters=2) and response statistics can they win it (js-session auto load url 2 if itch can switch)?

Level 2 have you complete it, for xp Sokoban player ? (if not do it, than top rate each other games? no/yes)
