just make sure when you go to each generator you have a feather and once you get stealth you can beat the game at around level 22. just kill everything you have to until the room with the generator then use stealth, hit the generator and feather teleport back to town
everyone is complaining about the limit of turns but that is the point of the game, you have a set time to accomplish your goal, which requires luck to find but if there was no limit on the turns the game would be simple and pointless
efrenl- if you step in the glowing circle in town it saves your game, if that works and it just deleted your progress when you turned off the game you might have your browser set up not to keep temporary internet files and cookies and such, you might need to change your security settings for it to be able to keep saves after you close the browser
oops forgot to mention, on mountain fire you upgrade the 6 middle spots to cold before you get passed the rounds strong against cold, otherwise you wont hurt the magic beetle at all
oh and mountain fire is really easy if you just spam mages everywhere without leveling them at all, then when you get passed to cold resist groups upgrade em all to cold
