1. Correct. There is currently no hybrid transformation in the game.
2. This is something im going to get to after I finish the new backgrounds. Its been a point of constant feedback, but i felt like the backgrounds looked really bad and i want to tackle that first. Should be done soon
3. Currently no. There will be for sure but right now you either escape or you dont. The method for escaping is filling up the pool meter all the way and then clicking on the path in the front outdoor area. That ending is still work in progress and will change in the future.
