I'm glad we have more people making Blockland Videos, though truth be told, you have much work to do.
Not trying to be mean or anything, but your intro looks like it was made in mspaint, and the bonk sounds are annoying, you might want to work on the pictures you use as a reference during the video as well, the basketball cuts off randomly but tank keeps going.
I want to help you out so I made you a better intro, take this image from down here and save it and when you do your into have it slide in from the left and then slide out the right, the light purple is transparent btw, the text is not transparent.
Why its purple? Well I thought it would fit in for some reason, wether purple is your color or not, too late to change it now, I still see it as a huge improvement though.
Good luck on the vids.
