Oh my goodness. Really appreciate the comment and the twitch stream link. (Thank you for recommending it to Jonathan!) We enjoyed watching and learning a lot from it.
Totally get the pixel art complaint. It was decision made to keep the game possible to make (due to my non existent art skills).
It has been a real honor to see people play the game and see how we could have improved it to have more consistent level groupings rather than "some art & difficulty".
Really helpful discussions and such useful criticisms. Will be keeping it in mind for our next game ^.^
