Thank you guys! I really appreciate the feedback. And you're right Alley, all the cousins are pretty evil. They're actually supposed to represent the seven deadly sins, so there's Glutton (gluttony), Sleepy (Sloth), Jelly (Envy/Jealousy), Mimi (Pride), Stingy (Greed), ...and I'm still working on names for the last two.
Also I really like your suggestions. Having a more extensive stage 1 in Grandma's forest/house would develop her character better. I think if I have her spawn outside of the house once the player has collected all of the candy, and then they walk to the house together using a timeline, I could change the location when they reach the door without ever interacting with the door object itself. It wouldn't make the opening/closing animation but I could mimic the sound in the timeline, it'd be close enough I think.
Thanks for noticing that about the sprekers and frenzies, I'll make an update so they behave lol. I also have an issue where the Jellis (octopus enemy) will escape the water in level 3 and jump around in the air... its a work in progress lol
