Pretty basic but seems to have a good foundation for more mechanics!

Just as you said, there's not a whole lot here at the moment, but that leaves a lot of room for additions and expansion. Like TheFriendlyEnemy said, it would've been nice to know that you interact with things via left click. Additionally, the walls to the left of the doors in the first house lack collision which was a little funny.  I noticed that for the first character, their sprite rotation would default to facing upwards. A way that you can fix this is by creating a variable that keeps track of which direction the character is facing and to only update that variable when an input is detected. There's probably a better way, but that's how I do it in my game. It's certainly a shame that you didn't get time to expand on the game more, but you can be proud knowing that what you have is at least playable!

I like the idea!
