From the preview video only,this looks great fun and very well put together,sure it's a mario clone...but that's the point!...it's a hark back to a golden era of video game history,when you could actually be playing a game that your friends are not!,and not feel bad about it...
Which brings me nicely onto the mostly negative,comments on steam...from so called "hard core" gamers...all playing call of drudgery 6,or similar...flaming someone for trying!...how original!!
At least you got up and did something positive...<tips hat>
Most on steam,will be too young to remember the early games...and will not have the memory associated attachment...fair enough...but a game made with passion should be on the top of any "hard core" gamers list.
Well done and don't lose heart..Kick ass!
