Great Rouge Game!

Played the game a few times and it is fun, but I somehow cant get past Lvl 10/11 it just goes down a Lvl or 2 when I go through a door/ level part, pls fix!!!
And when you dont Lvl up properly anymore, you also dont get any more stats :/
And an explanation of what each stat gives would also help a lot, spirit gives nothing from what I can tell...
