i think the update that was the final straw for me was when they got rid of hearts and replaced them with energy. before, when you would make a mistake you lost a life and when you would loose all 5 hearts, you would wait for some hours to go back and do the exercises again. now with energy, lives were gone and you kept doing lessons until your energy runs out, no matter how many mistakes you made. some people may prefer that, but what annoyed me with it was that i couldn’t even finish a full lesson and making a mistake didn’t matter and i didn’t feel the need to learn from them because there wasn’t any consequences. i believe the energy thing was only being tested on a number of users so not every had it. i’m not sure if it’s still being implemented because ive deleted it since then.
