Holy smokes - that's the kind of feedback I like to see, many thanks!! After reviewing it's positive views from the Jam, I think I will continue it to flesh it into a full game, with a few levels, and i'd like to make some kind of arcade mode where you're climbing for a high score.... May even look to make it GB Color compatible too and add a splash of color to the graphics!? Need a Hugetracker composer though, that's for sure!
Thanks again for the positive review!
