I have to solve this problem with the monitor, it didn't even cross my mind to use a lower resolution.
The idea was to fill the house with minigames that you should do before your mom gets home. Each character would have three minigames and the player would have to switch characters to make.
I had a tight time, I almost didn't deliver the game, I couldn't add the ambient audios, neither the music nor the sounds of footsteps.
The house was supposed to have more rooms and there would be a small dialogue with the father explaining to the children that the mother was almost there and that they should run to finish the tasks.
