@QuanML we have a rule at this forum that players simply comment on levels that they don't understand. The privilege of rating is only for those that complete the level. Unfortunately there is no way to delete ratings so please play the level again and leave a proper rating based on a full assessment of the gameplay, artistic merit, surprise factor, originality, etc.

P.S. the B bot is pushed out by the piston.

I'm with @Block builder, not much in terms of gameplay here. Perhaps you'd like to submit it instead to the Game Behaviours forum? I did like the fun surprise of B getting pushed out like that though. Thanks for sharing.
