Very cool concept, I can already see how much potential the game has and I'm excited to see where it goes in the future. I also think the reuse of assets here is really well done, considering the character customization and modularity of the transformations in OPP have so many ways they could be used outside of just the original game.
Overall, the idea of having a bunch of events and transformations on a path that you have to experiment with and test different combinations of is really interesting, and I think even a barebones prototype build like this shows that really well.
I'm also personally a sucker for the classic "cursed items" shtick, and I think the self transformations and POV stuff has alot of potential in combination with that. Some of the items kinda fell flat in OPP, but I think there's much more room for creativity with them here.
One small nitpick - I'm not really a huge fan of the cheek lines the character gets on their face on the 2nd stage of the blueberry sequence. I don't know if they're just a placeholder, but as is they just kinda make the character look old.
Regardless of that, though, the prototype build is still really fun, and it's got me very interested in seeing more from this game. Good luck with future development!
