I think this is a really unique concept, and I like that it explores a side of climate change and environmental damage that isn’t often discussed in games. The setting and story have a lot of emotional potential, especially with the laboratory gameplay and the relationship between the player and their cousin.
My biggest suggestion would be to keep the scope as focused as possible. There are a lot of systems and story moments planned, so concentrating on making one gameplay loop feel polished and satisfying will probably have a bigger impact than trying to include every planned feature. I think this project has a strong foundation, and I’m looking forward to seeing how it comes together over the rest of the jam.
