Thanks! i think the parts you enjoyed most were the ones i have the most experience in, this was kind of my first time doing a proper puzzle-platformer >v< especially for a game jam, there's plenty of things i'd like to change if i ever do a second pass on this idea.
As for using the idea yourself, go right ahead! i'd love to see more vore/unbirth-themed games myself...... 👀
I'm not particularly precious about my game ideas, especially jam entries like this, so i'm happy to serve as inspiration for others.
