The least I could ask for would be to have some way to tell how far you've gone and how much more you need to make it to the space station. Past that most of the other players that have left feedback are giving good comments and ideas for addition like music or better control of the character to not jump so high not be able to go down because you're stuck in hang-time in each jump. Even then it would still be a very basic game but nothing too offensive to hate with what you've made. I want to get the last medal but i don't know how far i'm expected to go and don't know if i've been close.
