Super thanks for the feedback, I managed to find you clip and left a comment.
Really interesting idea about a new area, I dont fully have an idea about the endgame or how to progress. I do have some "speical event" and more challanges stuff. Someone mention that it would be cool to have different types of block that do stuff with others, so yeah, lots of things to figure out and at the same time trying to keep the scope not too big!
Yeah I had coolmathgames on my list for potensial places to upload the Demo on once that is done, I am/was more of a newgrounds person however. ;)
