I JUST finnished the game ! it was really enjoyable and if you ever make it into a whole supermario like game it will be downloaded from a whole bunch of people including me! i would pay atleast 5 euro. Btw you can make world 1 have 10 games and the 10th to be the boss Super Mario based like. First world free second and third 5 euro and for the rest (as many worlds as you want) an other 5 euro
Any way, WELL DONE
