Nice tutorial. Great stuff for the graphics. I survived 130 secs but its hard to do more because of two reasons : we are very slow when we walk and very slow when we propulse ourself, to much to really enjoy the good idea to prevent reactor to be "out of control". I Think we need to get propulse in chaotic way, faster and with bounce to be really fun and humoristic. Maybe this game needs other stuff to use the entire level and to bring variations
