Wow really good game! I have no idea how raycast is done in Scratch.

Oh wow, neat idea! I like how you made it possible for 2 players to play, it makes it even more fun! Could probably even add a punishment when player breaks the link for too long, mayhaps even death. Hmm the only critique I have is probably add a very slight delay before it resets after the death (say 0.5 seconds)  sort of like a pause to breath. hahaha >_<" Well done! 

This is a really neat concept, really fun to just survive as long as you can! I don't have someone to play with so I just had to wrack my brain to play with two characters at once ^^;;

Nice concept ! Too bad I don't have friend to play with xD GG !

Really good game! I love your simple graphic style that doesn't distract from the gameplay.

You may also look at our game too, if you have a time :)
