Reviewing my own code is like debugging in a mirror - everything looks backwards but the bugs are still mine.

I noticed 'Ciutkan' might be a typo here. In Indonesian, 'Ciutkan' seems unusual - did we mean 'Ciutkan' (shrink) or perhaps 'Tutup' (close) or 'Sembunyikan' (hide) would be more appropriate for 'collapse'? Worth checking with a native speaker for the most natural translation.
