Yes, this game is fun. You start off as a little robot who can't see properly and can barely move. The thing I most enjoyed about it is the way you progress. Every time you find a part of yourself it allows you more freedom by giving you new abilities, allowing you to reach new places and upgrades. There is also kind of a storyline to it so it's not just aimlessly go around because you don't know what else to do. Since there are enemies that you can shoot, this is also not just your typical puzzle adventure game. The only thing that annoyed me was the way you had to go on roundabout ways to reach a place (though that gets fixed later on). If you're wondering what the metal plates are for, they fill in a hangman puzzle at the "end".
Summary: -Gameplay is good -Upgrading is fun! -Enemies are a plus -Storyline adds meaning to what you're doing
All in all I give this a 8,5. My score for it would be 8, though, because personally I am actually more of a action-type and the game didn't have enough of it, but thats just me.
p.S: My first reason for writing this was because, at the time of writing, I had the 2nd best score of 5590 (but 1st was more than a billion, clearly a cheater/hacker/or something, so I'm actually 1st ) and the 3rd was 5000. I just had to brag about it. However, there are only 71 people up till now, so it probably won't last forever.
