I'll post my reply here instead of on the game's page. It shares the title with an older Bitsy game by paradisemultimedia.
This little WIP was a treat to play! Though short, it's unique in all the cutscenes you made.
May I suggest using room dupes to quickly descend the stairs to the basement? (By using exits.) Or don't, if you want to make it longer to play.
PS: Once you get the mouse and go back to your computer, if you re-enter it, you CAN'T escape the pc screen room.
Overall, good job! Awaiting the finished product (amidst my other engines that I keep-up on of more games to play when I have time).
