Be careful

please give an impression and advice

Since you want 'impression and advice':

1st - welcome to the forum. I didn't enjoy this level at all. B is very hard to control even if you tap and cancel tap after one step. My first win was while I was attempting to get B around the white space to the other side, Z fell into the spot where the two Rs were bumping from the start redirecting them. One of the R's walked onto the win. My 2nd win was with B. 'Tall hard to control B' levels have been done before on this forum but I didn't like them either. For advise, less red herrings and more game play.

Hi & welcome...uuhhmm,I like this kind of levels & although this was very easy for me I add a star because I like the final move ...Thanks for sharing @Taufik

Thank you this is my first level, im sorry if this level much hard

Hi and welcome to the forum. One basic thing a Mekorama level should be is fun to play. Unfortunately, this is not. I won`t rate it, since it essentially just completes itself more often than not.
