I'm a really big fan of the concept. A few problems I had : I hate how fast Mario walks, pipes were very ignoring to enter, the first world was fun but it could of looked prettier imo ( I do understand the reasoning of the ground being the way it is. But it'd be nice if you could find a way to make the courses just pretty), music and sound effects would be really appreciated, I wish you had to obtain the fire flower like the big and small coin thing and lastly Id like to see a world map... I know this is a prototype and wont be like the final product but id like to see these things "fixed". idea for the game ( I kind of did add some ideas in the complaints thing but aw well...) : Different weather that can effect curtain things in the level.
