This is amazing update. I like the idea of final part but it's too hardcore(maybe some disbalance that make it hard). You probably need to lower speed, atleast for bunny part as you basically can't outran the thing. (I tried to not make a lot spoilers)
<Also idk if this intended but you can't pause mid running. So you forced to finish all. (It kinda gives vibes of self-aware games)>
