Criticism - The mouse sensitivity was a bit strange, despite the mouse settings to alter it. I could really never get a grip on the mouse movement. Also, in the webgl version the mouse sometimes teleports and looks somewhere else, completely ruining your flow. Figuring out how to fix the mouse movement and make it a bit more precise would definitely help this game.
Support - The art direction and implementation of the theme was amazing. The combo system made total sense within the theme and felt very important to the gameplay.
