I want to put my input here.
I think Sonny is an interesting game, fun as well. However, there are a few things I want to give my opinion about.
Stats: I think when you level up, at least 3 stats each should be given instead of 1. This way, it'd be easier to properly train your characters.
Attributes: I think Attributes should have a bigger impact on your abilities. This way, attacks could do more or less damage depending on the attributes.
Abilities: I think that abilities should increase in damage more on attributes and how much you've trained in it. This'd help because it'd give more of a bonus instead of just increased % for something.
That is all.
