I'm 90% sure that the new belly size will be the last 'playable' size, but I'm considering one more 'immobilized' size that can be achieved by devouring certain oversized enemies.
That's exactly what I was thinking about! It's amazing to see how well planned out you have this game. While I like offering idea's. It's just overall better seeing a creator who has already considered everything. Let alone someone who is doing an amazing job like yourself!
