You know those silly “Mon Hid My Game!” games I played a while back? This is one of them, only with a slight difference.
Each level, you have to hide from your sister. The first few are easy – behind a curtain, or in a cupboard – but they soon get more complicated. The gameplay, such that it is, is almost exactly like the other games and it has some similar 4th wall breaking “surprises” later on, but it’s a bit of silly fun for a low price, so why not, eh?
