Wow! Such an awesome game! Such good mechanics and graphics! Such a thoroughly made game is the last thing that I would expect in a game jam with such a time limit. There are still some things to improve:
1) Why doesn't the game have an itch.io page? (But this is minor, not so important.)
2) You should have properly explained that you can press Q anytime to switch characters. It took me long to understand this. I restarted the game two times because I didn't understand it and thought that the game was bugged.
Otherwise, the game is brilliant! I liked:
1) The character-switching mechanics are cool! (You should have only explained it better.)
2) The graphics and the look of the critters are good.
3) The audio part of the game and the half-horror atmosphere were nice.
4) The game takes place in a quite big map with several locations.
5) I would consider points 1-4 nothing special if this was a paid triple-A game. How did you manage to create such a masterpiece in nine days? That's incredible!
This game might win the jam.
PS: Your game uses the Button Smash and Rage Room wildcards. However, I didn't spot a quick-time-event or a rage room in the game. Does the game contain some secrets that I didn't find?
