If you have trouble to getting trough the game but want the achievement here your go!

You can edit your savegame file. (I'm not sure if it's different in Windows 10, I'm using windows 7)

Close game > Windows + R ( Run ) > %appdata% > Local

go to the dungetris folder and open your profile data

now you can change whatever you want most simple is just edit > warrior="1.000000"
or whatever character you prefer
here you just change the 1 to 900 and you will have no problem going through every level.
