Great game! Though I think there can be a few balance adjustments. I played on casual because I'm a casual guy, but there's a couple of frustrating situations.
I think the hit range when breaking free should be slightly increased, I have had a handful of situations where if an enemy is just far enough, I will break free of a hold, but will instantly get grabbed again because an enemy was barely out of the breaking free range.
In terms of specific enemies, the dogs can be frustrating on the later levels when combined with several enemies. They have a lot of health, can only be hit with low attacks, get launched pretty far when hit, and sometimes I've had them just stop moving, forcing me to have to move to them myself.
On their own its no big deal, but when combined with enemies, it feels like rolling past enemies is no longer an option, forcing you to just sorta sit there. I hit a dog, he gets launched behind several traps and enemies, now I have to fight those enemies, and I can't roll past because of the dog/traps. It's like everytime there is specifically a dog, I cannot move until every enemy on screen is dead, making especially the last level pretty rough.
Personally, since it's a rather small dog, I think it should move quick but have low health. Or maybe you can just jump over them entirely, I found it surprising they couldn't be jumped over.
As I said I'm a casual, but those last couple of levels certainly did not feel casual, I was struggling and those two were my biggest frustrations.
Other then that, great work! And I look forward to the rest of the cast being released.
