It's a disgrace, not a game.
First of all, "It's a very early test", and as far as I remember Tom has asked to not post unfinished verions of games on the portal. You have dumping grounds for it, and a basic "run movie" option in flash, and I guess you could just do with that, since I see no any connection features in here.
About the "project" itself: It's another unoriginal mario styled game. The level is very short, there is no replay button or anything in case if you lose, or win to restart the "game". Some of the graphics were straight ripped from Mario, some have been changed. To worse I guess. I understand this must be some kind of refference to Blowers Brothers which I haven't even heard of, but don't worry. I do not follow any news these days.
In addition I must mark that jumping in this game is very bongish, and you can't even harm goombas.
I'd give it like 2 or 3 stars for music, but this is not a game yet.
