The art is simple yet good, the plot is interesting, and the gameplay is simple, but still good; my problem is that it has frozen on me twice now on the same part and since there is no save function or skip button, I have to wait through the same cutscenes and play through the same parts again.
It keeps freezing just after I beat the first part of the cat level (note: I beat the game once already; the only difference in the playthroughs is that I went straight for the third toilet instead of playing through the first and second toilet).
