when turning on POM:
moving_block: moving_block: ERROR: 0:897: '||' : wrong operand types no operation '||' exists that takes a left-hand operand of type '2-component vector of highp bool' and a right operand of type '2-component vector of highp bool' (or there is no acceptable conversion)
ERROR: 0:897: '||' : wrong operand types no operation '||' exists that takes a left-hand operand of type 'const highp bool' and a right operand of type '2-component vector of highp bool' (or there is no acceptable conversion)
ERROR: 0:897: '||' : wrong operand types no operation '||' exists that takes a left-hand operand of type 'const highp bool' and a right operand of type '2-component vector of highp bool' (or there is no acceptable conversion)
ERROR: 0:898: 'any' : no matching overloaded function found (using implicit conversion)
ERROR: 0:898: 'any' : function is not known
ERROR: 0:897: '=' : cannot convert from 'const float' to 'highp bool'

should be fixed now, just download the latest code from main.
