the begining is just too boring, then you get the lvl 3 to make little fun, but it's fastly becoming long after that. You could put more obstacle or for the green wall, it will be funnier if you have to break it by doing an action, like if there's a wall we need to press "d" to cut it with a weapon. Also, press "s" to pass under some walls. Then, your game could be really good, but it need some modification and i gave you 1.5/5 stars for the effort.
