Sometimes I've thought how B can pass through a block. It isn't possibile. Caken discovered a bug in his level "BiggerBot" ; a brown block can pass through another brown block. I've thought what happens If I put B in a cage and this cage can pass through a big mass of brown blocks. What do you have to do in this level is simple: move very fastly the motor, you will have a schocking surprise (probably the best surprise you've seen on mekorama).
Wow another new discovery? Nice! With this machine, sometimes can turn B to ghost too. Mutiple purposes =D. btw this reminds the movie Jumper (2008).
Haha the bug with metal block was already fun, now with B it's incredible! What happened to your last screenshot? You played again with zappers or discovered a new way for blocks to become invisible? That is really strange
