Development will continue! What should I add?

This game has seen a lot more success than I'd ever imagine. Nearly 4,000 views and almost 400 downloads! (at the time of writing this) It's absolutely insane, thanks to everyone who played! With all the positive reception and attention this game has received, I've decided to continue developing it!

I have a few ideas on where to go from the current game, but right now the plan is to split the game into 3 acts. The current game will be Act 1, and the next two acts will be of similar length. Each act will have a different creature you play as with it's own moveset, and potentially a new machine to deal with as well. If I do end up doing this, the game will need a new name because it'll no longer be about just a rat.

There's a lot of directions I can take this game, so please let me know what you'd like to see expanded upon! More platforming? More attacks from the Machine? Is my 3-act idea worth pursuing, or should I keep the game short and sweet? I want to make this game truly special, so I'd really appreciate your guy's ideas!
