I haven't reached any endings but been noticing some transformations
Easiest one is the appleseed transformation, having 5 different stages. You can just pay 10 constantly to get 10 seeds, or pay 50 to get 50 seeds. It happens everytime from my experience and I've been playing for about 5h straight now (help)
Then's the bug/insect transformation, it's tricky and I've only seen one stage of it. Been slowly eating appleseeds so I remain normal and not starved while saving up insect foods. Leeches don't seem to count toward this, idk about snails. Worms do. I've only seen 1 stage of this transformation
Idk about rest, only drinking sodas leads nowhere from what I've seen
If you pay 500 you often get objects?... I feel like eating multiple objects in a short time period might give some new transformation path
Then there's human related items like the baby looking thing and eyes. Could also lead somewhere, I haven't gotten enough of those items to dare and try (edit: doesn't seem to lead anywhere, ate about 6 of these items. Maybe they negate each other somehow or just don't have transformation path)
