The game was really simple but confusing at the same time.
I reached the final without even try the button "flip" but because I was scared of "everything is reset except..". I wasnt able to understand that part until I reached 100 light by just waiting a long time to get other empowers.
Maybe a better UI or changing the font too, I was having a kind of a hard time trying to read everything. The rest is pretty nice!
Sadly once you reach the final, there is no point in keep playing it.
