wtf
here are some things to improve-
-make the ? blocks in range of marios jump
-make the ? blocks work
-make more than 2 ? blocks
-make it possible to beat it within the time limit
-make it so that you can play it more than once, the second time you play it you get an automatic game over
-make it so that the graphics are better (some of the pipes had chunks missing)
-put in music and sounds
-overall, make it better
