I think RobTop did a great job on developing such a simple game that can be so hard. I like how you have limitless possibilitys while creating or, playing a level. but there are a few bugs that get me mad like sometimes when im playing a level in will teloport me to a spike and make me die. but another good thing is the game never gets boring ive been playing this game for six years and im currently still addicted too the game. if you want to play the game i recommend the full version. great game
