Really liked the art style, but it is a shame that there was no sound whatsoever.
This game reminded me a lot of binding of isaac and nuclear throne, both games I adore, so you certainly have my attention.
I just think that there needs to be some kind of feedback for when you hit an enemy, and the out of control thing felt a little tedious.
However, I am really amazed that this is a game jam game, and really just feels like an alpha of a full game with awesome graphics. I really think you could develop this into something more.
