The barrel does not discriminate, love the idea of explosive chain reaction, it does make me feel smart when I can utilized it to blow the enemy, but at some point seeing that it can blow up the dragoon as well made me a bit too cautious when to blow the barrel. Maybe saving that interaction to a gimmick level would have a nicer 'break expectation' would be nicer in my opinion. (Because I do really love that house full of explosive level!).
Beside that, overall a fun game!
