to be honest I'm a Construct n00b
I've added a FPS txt so if you redownload my capx example it'll have a FPS reading
was testing it in firefox stayed around 45-60
chrome worked for me well in beginning but then dipped to around 25-30 fps once it hits your wait function when get the correct ans or go over your goal. Maybe rather than use WAIT make a end level notice and set timescale = 0 so it pauses game and then have user hit R to restart or a dif button
not sure exactly what mean by feels heavy?
I haven't really experimented with C2 as much as I'd like yet
real job and life gets in the way.
As for the tongue retract just make addtl action when tongue hits fly to destroy tongue
but with your coding right now unsure if that'd work
